Windows 8

Windows 8 is a version of Microsoft Windows (an operating system developed by Microsoft) for use on personal computers, including home and business desktops, laptops, tablets, and home theater PCs. Development of Windows 8 started before the release of its predecessor, Windows 7, in 2009. Its existence was first announced at CES 2011, and followed by the release of three pre-release versions from September 2011 to May 2012. The operating system was released to manufacturing on August 1, 2012, and was released for general availability on October 26, 2012. Windows 8 uses version 6.2 of the Windows NT kernel.

Windows 8 introduces significant changes to the operating system's platform, primarily focused towards improving its user experience on mobile devices such as tablets to better compete with other mobile operating systems like Android and Apple's iOS. Windows 8 features a new touch user interface and shell based on Microsoft's "Metro" design language, featuring a new Start screen with a grid of dynamically updating tiles that represent applications. The Start screen replaces the "Start menu" of earlier Windows versions. There is a new app platform with an emphasis on touchscreen input, and the new Windows Store to obtain and/or purchase applications to run on the operating system.

In addition, Windows 8 takes advantage of new or emerging technologies like USB 3.0, 4Kn Advanced Format, near field communications, cloud computing, and the low-power ARM architecture. It includes new security features such as built-in antivirus capabilities, a new installation process optimized for digital distribution, and support for secure boot (a UEFI feature which allows operating systems to be digitally signed to prevent malware from altering the boot process). Synchronization of certain apps and settings between multiple devices is supported.

Windows 8 was released to mixed reception. Although reaction towards its performance improvements, security enhancements, and improved support for touchscreen devices was positive, the new user interface of the operating system has been widely criticized for being potentially confusing and difficult to learn (especially when used with a keyboard and mouse instead of a touchscreen). Despite these shortcomings, 60 million Windows 8 licenses have been sold through January 2013. This includes upgrades and sales to OEMs for new PCs.

Windows 8.1 is scheduled for later in 2013, and according to Microsoft will change "key aspects" of how Windows 8 is used.

New Features in Windows 8

I have been talking and writing about new Windows versions since the days of Windows XP but believe me I was never as excited as I am today as I begin to share some of the new changes and features Windows 8 will bring about. Of course we’ve revealed some of that before but today, after having helped you take a peek into the dev preview, this article dives deep into what’s new in Windows 8.

Now, not all of the features might appeal to the average user out there. Keep in mind that Windows 8 is more of a tablet-centric OS. For a geek like me, it brings some significant changes but am still not sure how the average user will rate these some of these new stuff. Not taking much of your time I’ll straight-away take you to the most prominent new changes you will see in Windows 8 and leave it up to you to decide what do you like and what you’d rather not see in this upcoming Windows version.

1. Performance Increases

 

One of the issues that's been on our minds since they first previewed this new interface was whether this will keep bogging Windows down with more running processes, and whether running a full Windows desktop on a low-powered tablet was really a good idea (after all, we've seen Windows run on netbooks).

Microsoft knows your fears, and has addressed them: Windows 8 is slated to have better performance than Windows 7, even with this metro interface running on top of a desktop. We ran a few tests back when the the Developer Preview came out and found that to be the case, especially when it comes to boot times. Tablet users and netbook users especially should notice a fairly significant performance increase with Windows 8. Especially considering that any of your tablet-based apps will suspend themselves when you jump into the traditional desktop, so all they take up is a little of that extra RAM.

2. The Lock Screen

 

Windows 8's lock screen is pretty much what you'd expect: it's got a beautiful picture along with a few little widgets full of information, like the time, how many emails you have, and so on. You can swipe up to unlock, or press the spacebar if you're on a desktop keyboard. You can then proceed to type your normal password, or use one of Windows 8's "picture passwords," which let you swipe or draw an invisible gesture that only you know, using your lock screen photo as reference, to let yourself in (though this is really better on tablets than it is on a PC). For example, in Microsoft's original demo, they used a photo of a person, and the password was to tap on their nose and swipe left across their arm).

3. The Start Screen

Once you log in, you're taken to Windows 8's new Start screen, which replaces the old Start menu. The screen should be familiar to Windows Phone users: You've got a set of tiles, each of which represents an application, and many of which show information and notifications that correspond to the app. For example, your email tile will tell you how many unread emails you have (and who they're from), your calendar tile will show upcoming events, your music tile will show you what's playing, and so on. You can also create tiles for games, contacts, and even traditional Windows apps that will pull you into the Windows desktop. The tablet-optimized apps are all full screen and "immersive", though, and you can rearrange their icons on the home screen easily (just as you would on any other tablet platform). At any time, you can press Win+D or click on the Desktop tile to go to the familiar Windows desktop instead.

4. The Desktop

Once you get to the desktop, you'll be in much more familiar territory. You've got your taskbar, your desktop icons, and your normal windowed applications as you're used to (though they have a new, flatter, Aero-less theme). The Start menu, however, is gone—instead, you can move your mouse to the bottom left hot corner and click to return to the Start screen, or press the Windows key as normal. Like the old Start menu, you can start typing any time you're on the Start screen to start searching for an app or setting, giving you quick access to everything on your computer.

It isn't nearly as convenient as the old Start menu was, but you can get used to most stuff pretty quickly. Pressing the Windows button and typing in an app or setting is faster than browsing the Start menu anyway, so it's a good habit to get into, and you can always access a more traditional menu by pressing Win+X—this will bring up a small menu in the corner that has shortcuts to the Control Panel, Run, the Command Prompt, and other stuff advanced users may want to access.

5. Full Screen Apps

While you can pin your favorite apps to the taskbar, as usual, most of your apps will reside on the Start screen, just like they used to reside in the Start menu. Just fire up the Start screen and tap or click on the tile for the app you want to launch (or, as we mentioned above, type it in the search box). Tablet-optimized apps will go full screen, while others will shoot you back to the desktop.

The full-screen apps that come with Windows 8 are really nice: most have touch-based controls, like pinch to zoom and copy and paste, but you can also use them with a mouse and keyboard if you so desire. Each has options like search, share, and settings through the Charms bar, which you can get by swiping from the right edge of the screen or pressing Win+C. Apps can share information one another easily, such as selected text or photos. After picking your media from one app, you'll then be able to choose which app you want to share with, and work with it from there. For example, you can share photos to Facebook, send text from a web page in an email, and so on.

None of this is brand new to touch-based platforms, but what is new is the ability to not only multitask, but run these apps side by side. Say you want to watch a video and keep an eye on your news feed at the same time. Just like in Windows 7 for the desktop, you can dock an app to one side of the screen while docking another app at the opposite side, which is a seriously cool feature. Imagine being able to IM and play a game at the same time, or browse the web while writing an email. It's a fantastic way to fix one of the big shortcomings of mobile OSes, thus allowing you to ignore the full desktop interface more often and stay in the touch-friendly, tablet view.

6. The Windows Store

The Windows Store looks much like the home screen, with tiles that correspond to different categories and featured apps. From there, you can look at a more detailed list of the available apps in a given section. And, the store contains not only touch-based apps for the tablet interface, but some of the more traditional desktop Windows apps you're used to, so you have one portal to discover all your Windows apps no matter what interface you're using. The Store has free and paid apps, and you can try paid apps before you commit to buying, which is really, really nice.

7. Sync All Your Data to the Cloud

The cloud is taking center stage in Windows 8, with your Microsoft account driving all the syncing. Your address book, photos, SkyDrive data, and even data within third-party apps can sync up to the cloud, and you can access them on any Windows 8 device—even a brand new one. Just sign in, and you'll have access to everything (not unlike Chrome OS, which immediately loaded your themes and extensions when you logged in). The address book also syncs with other services like Facebook and Twitter as well. You can even sync all of your settings from one Windows 8 PC to another. Just sign onto your Windows 8 with a Microsoft account and you'll get all your themes, languages, app settings, taskbar, and other preferences will show right up. It's a pretty neat feature if you have multiple Windows 8 PCs and don't want to set them all up separately—just a few taps and you've got all your preferences ready to go (you will have to re-download your apps, though).

8. Windows Explorer

Windows Explorer has gone through a few changes this time around, most notably the "Ribbon" interface we've come to know from Microsoft Office. Instead of traditional menus like View, you now have three Ribbon panes: Home, Share, and View, that give you access to the features that used to be in the menus. If you're in a folder designed for certain file types—like the "Pictures" library—you'll get a few extra Ribbon panes centered around photos, which is pretty cool. Windows Explorer also has native mounting of ISO files, a one folder up button like the old days of XP (thank God), and a really cool "quick access" toolbar in the left-hand corner that lets you add your favorite shortcuts to the title bar. It also has a new file copy dialog that makes it easier to manage move-and-replace actions with lots of files.

9. A New Task Manager

Microsoft's finally redesigned the task manager, and it looks pretty great. You have a very simple task manager for basic task killing, but if you're a more advanced user, you can bring up the detailed task manager filled with information on CPU and RAM usage, Metro app history, and even startup tweaking—so you can get rid of apps that launch on startup without going all the way into msconfig.

10. Built-In Antivirus with Windows Defender

Remember Microsoft Security Essentials, our favorite antivirus app for Windows? Well, now it's built in to Windows 8 as Windows Defender. It has nearly the exact same interface and feature set; the main difference is that you no longer have to install it.

11. Internet Explorer 10

Your all new Windows will come along with an all new browser, Internet Explorer 10. Microsoft has promised to deliver enhanced speed and flawless security with a better HTML5 support. Unlike me if you love working in IE (I prefer Chrome) do let us know about your experience using the all new Internet Explorer.

12. Better File Operations

Remember how we insisted on using tools like Teracopy and Supercopier to achieve faster file and folder copying in Windows? Well you can forget them once you install Windows 8. The three primary aspects that will change in file operations are:
Queuing of multiple file when copying with more control with ability to pause and resume each file being copied or moved. Users can also view the source or destination folder while the process is running.

 

Windows 8 will feature enhanced real-time information on how long it will take to copy a file unlike the crappy clocks of previous versions of Windows. Users will be able to see operational graphs, transfer speeds as well.

 

13. Faster Hybrid Boot

 

Now this is one of the most revolutionary changes that will come about with Windows 8 -  the Hybrid Boot support. This feature will combine the shutdown and hibernate process of earlier version of Windows thus booting Windows in 8 to 10 seconds on supported machines.

14. USB 3.0 Support

Windows 8 will support USB 3.0 and thus the entire machine which has the necessary hardware can now enjoy faster copy/move operations.

15. Other Features

Along with these cool features, Windows 8 also comes with other features we've come to know and love to see in desktop and mobile OSes alike. It's got system-wide spellchecking, so you don't have to rely on a specific app to keep your writing top-notch, as well as a system-wide search feature, that lets you search anything from your music library to your contacts to the web itself. It also has a really cool feature for desktop users that lets your run the Metro UI on one monitor while running the traditional desktop on the other (not to mention better support for multiple monitors in general—like having the taskbar on both screens).

It also has a really cool feature called "refresh your PC", where you can do a clean install with the tap of a button. Whether you're selling your machine or just want a cleaner, faster installation of Windows, you can do it all in one click. You can even set refresh points, similar to restore points, so you can refresh your PC to the way it was at a certain point in time.

Windows Mobile

Windows Mobile is a family of mobile operating systems developed by Microsoft for smartphones and Pocket PCs. Windows Mobile is the predecessor of Windows Phone. In February 2010, Microsoft announced Windows Phone to supersede Windows Mobile, with the new operating system incompatible with Windows Mobile devices and software. As a result, Windows Mobile has been discontinued.

The final version of Windows Mobile, released after the announcement of Windows Phone, was 6.5.5. Microsoft has stated that the Windows Phone operating system is incompatible with devices designed for Windows Mobile as "Windows Mobile 6.x devices do not meet Windows Phone hardware requirements designed to ensure a consistent user and developer experience", and software designed for Windows Mobile is incompatible with the new operating system.

Device of Windows Mobile

Microsoft’s first mobile operating system was Windows CE, which stood for Compact Edition. It was based on extremely stripped down Windows 95 code. In creating Windows CE, Microsoft removed the APIs for everything that wasn’t absolutely critical so that they could make Windows small enough to run on a mobile device. Of course back then there were no Windows phones. The first Windows CE devices were little more than glorified PDAs.
Over the years, Windows CE has gone through quite an evolution. The picture that follows shows several Windows Mobile devices and, except for the Windows Phone 7 device, all of them were based on Windows CE code.

The device shown in the upper left corner of the figure is an HP Jornada, which runs Windows CE 2.0. The Jornada (which I purchased somewhere around the year 2000) functioned similarly to a mini laptop but couldn’t run applications that were designed for desktop versions of Windows. The device was really quite extraordinary for the time period but ultimately never caught on because of its $1,000+ price tag. In case you are wondering, the thing that made this device so costly was that it was one of the first mobile devices to include a color screen.

History

Windows Mobile was based on the Windows CE kernel and first appeared as the Pocket PC 2000 operating system. It was supplied with a suite of basic applications developed with the Microsoft Windows API, and is designed to have features and appearance somewhat similar to desktop versions of Windows. Third parties can develop software for Windows Mobile with no restrictions imposed by Microsoft. Software applications were purchasable from Windows Marketplace for Mobile during the service's lifespan.

Most early Windows Mobile devices came with a stylus, which can be used to enter commands by tapping it on the screen. The primary touch input technology behind most devices were resistive touchscreens which often required a stylus for input. Later devices used capacitive sensing which does not require a stylus. Along with touchscreens a large variety of form factors existed for the platform. Some devices featured slideout keyboards, while others featured minimal face buttons.

1. Windows CE

Microsoft's work on handheld portable devices began with research projects in 1990, two years later work on Windows CE officially began. Initially the OS and the user interface were developed separately. With Windows CE being based on Windows 95 code and a separate team handing the user interface which was codenamed WinPad(later Microsoft At Work for Handhelds). Windows 95 had strong pen support making porting easy; with some saying "At this time, Windows 95 offers outstanding pen support. It is treating pens right for the first time." WinPad was delayed due to price and performance issues, before being scrapped in early 1995 due to touchscreen driver problems relating to WriteTouch technology, made by NCR Microelectronic Products. Although WinPad was never released as a consumer product, Alpha builds were released showcasing many interface elements. During development of WinPad a separate team worked on a project called Pulsar; designed to be a mobile communications version of WinPad, described as a "pager on Steroids". This project was also canceled around the same time as WinPad. The two disbanded groups would form the Pegasus project in 1995. Pegasus would work on the hardware side of the Windows CE OS, attempting to create a form factor similar to a PC-esque PDA like WinPad, with communications functionality like Pulsar. A hardware reference guide was created and devices began shipping in 1996, although most of these device bore little resemblance to the goal of a pen-based touchscreen handheld device.

2. Pocket PC 2000

Pocket PC 2000, originally codenamed "Rapier", was released on April 19, 2000, and was based on Windows CE 3.0. It was the debut of what was later dubbed the Windows Mobile operating system, and meant to be a successor to the operating system aboard Palm-Size PCs. Backwards compatibility was retained with such Palm-Size PC applications. Pocket PC 2000 was intended mainly for Pocket PC devices, however several Palm-Size PC devices had the ability to be updated also. Further, several Pocket PC 2000 phones were released, however Microsoft's "Smartphone" hardware platform was not yet created. The only resolution supported by this release was 240 x 320 (QVGA). Removable storage card formats that were supported were CompactFlash and MultiMediaCard. At this time Pocket PC devices had not been standardized with a specific CPU architecture. As a result, Pocket PC 2000 was released on multiple CPU architectures; SH-3, MIPS, and ARM. Infrared (IR) File beaming capability was among the original hardware features.

The original Pocket PC operating system had similar appearance to Windows 98, Windows Me, and Windows 2000 operating systems.

This initial release had multiple built-in applications, many of them similarly branded to match their desktop counterparts; such as Microsoft Reader, Microsoft Money, Pocket Internet Explorer and Windows Media Player. A version of Microsoft's Office suite called Pocket Office was also bundled and included Pocket Word, Pocket Excel and Pocket Outlook. Notes, a written and sound note-taking application saw its first release and would be supported by most later versions of Windows Mobile. Character recognition support allowed Notes to distinguish styles of handwriting to be learned by the OS during processing to improve accuracy and recognition levels.

2. Pocket PC 2002

Pocket PC 2002, originally codenamed "Merlin", was released in October 2001. Like Pocket PC 2000, it was powered by Windows CE 3.0. Although targeted mainly for 240 × 320 (QVGA) Pocket PC devices, Pocket PC 2002 was also used for Pocket PC phones, and for the first time, Smartphones. These Pocket PC 2002 Smartphones were mainly GSM devices. With future releases, the Pocket PC and Smartphone lines would increasingly collide as the licensing terms were relaxed allowing OEMs to take advantage of more innovative, individual design ideas. Aesthetically, Pocket PC 2002 was meant to be similar in design to the then newly released Windows XP. Newly added or updated programs include Windows Media Player 8 with streaming capability; MSN Messenger, and Microsoft Reader 2, with Digital rights management support. Upgrades to the bundled version of Office Mobile include a spell checker and word count tool in Pocket Word and improved Pocket Outlook. Connectivity was improved with file beaming on non-Microsoft devices such as Palm OS, the inclusion of Terminal Services and Virtual Private Networking support, and the ability to synchronize folders. Other upgrades include an enhanced UI with theme support and savable downloads and WAP in Pocket Internet Explorer.

3. Windows Mobile 2003

Windows Mobile 2003, originally codenamed "Ozone", was released on June 23, 2003, and was the first release under the Windows Mobile banner. It came in four editions: "Windows Mobile 2003 for Pocket PC Premium Edition", "Windows Mobile 2003 for Pocket PC Professional Edition", "Windows Mobile 2003 for Smartphone" and "Windows Mobile 2003 for Pocket PC Phone Edition". The last was designed especially for Pocket PCs which include phone functionalities. The Professional Edition was used in Pocket PC budget models. It lacked a number of features that were in the Premium Edition, such as a client for L2TP/IPsec VPNs. Windows Mobile 2003 was powered by Windows CE 4.20. Communications interface were enhanced with Bluetooth device management. Which allowed for Bluetooth file beaming support, Bluetooth headset support and support for Bluetooth add-on keyboards. A pictures application with viewing, cropping, e-mail, and beaming support was added. Multimedia improvements included MIDI file support as ringtones in Phone Edition and Windows Media Player 9.0 with streaming optimization. A puzzle game titled Jawbreaker is among the preinstalled programs. Other features/built-in applications included the following: enhanced Pocket Outlook with vCard and vCal support, improved Pocket Internet Explorer and SMS reply options for Phone Edition.

4. Windows Mobile 2003 SE

Windows Mobile 2003 Second Edition, also known as "Windows Mobile 2003 SE", was released on March 24, 2004 and first offered on the Dell Axim x30. This was the last version which allowed users to back up and restore an entire device through ActiveSync.

This upgrade allows users to switch between Portrait and Landscape modes and introduces a single-Column layout in Pocket Internet Explorer. To make wireless internet access more secure Wi-Fi Protected Access (WPA) support was added. An array of new screen resolutions also debuted;VGA (640×480), 176х220, 240x240, and 480x480, to increase visual clarity and the range of form factors Windows Mobile could run on.

5.  Windows Mobile 5

Windows Mobile 5.0, originally codenamed "Magneto", was released at Microsoft's Mobile and Embedded Developers Conference 2005 in Las Vegas, May 9–12, 2005. Microsoft offered mainstream support for Windows Mobile 5 through October 12, 2010, and extended support through October 13, 2015. It was first offered on the Dell Axim x51. It used the .NET Compact Framework 1.0 SP3, an environment for programs based on .NET. Windows Mobile 5.0 included Microsoft Exchange Server "push" functionality improvements that worked with Exchange 2003 SP2. The "push" functionality also required vendor/device support With AKU2 software upgrades all WM 5.0 devices supported DirectPush. This version featured increased battery life due to Persistent storage capability. Previously up to 50% (enough for 72 hours of storage) of battery power was reserved just to maintain data in volatile RAM. This continued the trend of Windows-based devices moving from using RAM as their primary storage medium to the use of a combination of RAM and flash memory (in use, no distinction between the two is obvious to users). Programs and frequently accessed data run in RAM, while most storage is in the flash memory. The OS seamlessly moves data between the two as needed. Everything is backed up in the flash memory, so unlike prior devices, WM5 devices lose no data if power is lost. New to 5.0, OS updates were released as Adaptation kit upgrades, with AKU 3.5 being the final released.

A new version of Office was bundled called "Microsoft Office Mobile" with includes PowerPoint Mobile, Excel Mobile with graphing capability and Word Mobile with the ability to insert tables and graphics. Media management and playback was enhanced with Picture and Video package, which converged the management of videos and pictures and Windows Media Player 10 Mobile. Among new hardware features were enhanced Bluetooth support, default QWERTY keyboard-support and a management interface for Global Positioning System (GPS). Improvements were made to ActiveSync 4.2 with 15% increased synchronization speed. Business customers benefited from a new error reporting facility similar to that present in desktop and server Windows systems. Caller ID now supports photos so a user can apply an image to each contact to show when a call is received. DirectShow was also natively added.

Windows Mobile 5.0 requires at least 64 MBs of ROM (it's advisable to have 64 MBs of RAM), and the device must run an ARM compatible processor such as the Intel XScale or the Samsung and Texas Instruments ARM compatibles.

6.  Windows Mobile 6

Windows Mobile 6, formerly codenamed "Crossbow", was released on February 12, 2007 at the 3GSM World Congress 2007. It comes in three different versions: "Windows Mobile 6 Standard" for Smartphones (phones without touchscreens), "Windows Mobile 6 Professional" for Pocket PCs with phone functionality, and "Windows Mobile 6 Classic" for Pocket PCs without cellular radios.

Windows Mobile 6 is powered by Windows CE 5.0 (version 5.2) and is strongly linked to the then newly introduced Windows Live and Exchange 2007 products. Windows Mobile 6 Standard was first offered on the Orange's SPV E650, while Windows Mobile 6 Professional was first offered on the O2's Xda Terra. Aesthetically, Windows Mobile 6 was meant to be similar in design to the then newly released Windows Vista. Functionally, it works much like Windows Mobile 5, but with much better stability.

Along with the announcement of Office Mobile 6.1with support for Office 2007 document formats (pptx, docx, xlsx); OneNote Mobile, a companion to Microsoft Office OneNote was added to the already installed version. In addition to the newly included programs with Office Mobile improvements were made to existing applications. Such as HTML email support in Outlook Mobile. A large number of Windows Mobile users are enterprise users business environments were targeted. With Server Search on Microsoft Exchange 2007, Out of Office Replies with Microsoft Exchange 2007, and search ability for contacts in an Exchange Server Address Book being implemented. To aid development for programmers, .NET Compact Framework v2 SP2 is now preinstalled with the OS. Developers and users also have access to Microsoft SQL Server 2005 Compact Edition for storage and retrieval of information. AJAX, JavaScript, and XMLDOM support were added to Internet Explorer Mobile along with improved devicewide Internet Sharing. Communication abilities were further enhanced with a new Microsoft Bluetooth Stack and VoIP (Internet calling) support with AEC (Acoustic Echo Cancelling) and MSRT Audio Codec.

To improve security Microsoft added Storage Card Encryption so that encryption keys are lost if device is cold-booted. Further updates both, security and feature, can now also be provided using Operating System Live Update.

7.  Windows Mobile 6.1

Windows Mobile 6.1 was announced April 1, 2008. It is a minor upgrade to the Windows Mobile 6 platform with various performance enhancements and a redesigned Home screen featuring horizontal tiles that expand on clicking to display more information, although this new home screen is featured only on Windows Mobile Standard edition. This was not supported in the Professional edition. Several other changes such as threaded SMS, full page zooming in Internet Explorer and 'Domain Enroll' were also added, along with a "mobile" version of the Microsoft OneNote program and an interactive "Getting Started" wizard. Domain Enroll is functionality to connect the device to System Center Mobile Device Manager 2008, a product to manage mobile devices. The most apparent of the other differences is that the Standard version (like prior versions) still creates automatic links for telephone numbers in Tasks and Appointments, which allows for the easier click and dial of stored telephone numbers within these Outlook items. This feature is not supported in the Professional version. Windows Mobile 6.1 also had improved bandwidth efficiency in its push-email protocol "Activesync" of "up to 40%"; this considerably improved battery life in many devices.

Aside from the visual and feature distinctions, the underlying CE versions can be used to differentiate WM6.0 from WM 6.1. The version of Windows CE in WM 6.0 is 5.2.*, with the final number being a 4 digit build ID (e.g. 5.2.1622 on HTC Wing). In WM 6.1, the CE version is 5.2.* with a 5 digit build number (e.g. 5.2.19216 on Palm Treo 800w).

7.  Windows Mobile 6.5

Windows Mobile 6.5 was a stopgap update to Windows Mobile 6.1 intended to bridge the gap between version 6.1 and the then yet-to-be released Windows Mobile 7 (Later renamed Windows Phone 7), that arrived in 2010. It was never part of Microsoft's mobile phone roadmap, and has been described by its chief executive, Steve Ballmer, as "not the full release [Microsoft] wanted" until the multi-touch-enabled Windows Mobile 7 (now replaced by Windows Phone) arrived in 2010. Ballmer also indicated that the company "screwed up with Windows Mobile", he lamented that Windows Mobile 7 was not yet available and that the Windows Mobile team needed to try to recoup losses. Microsoft unveiled this version at the 2009 Mobile World Congress in February, and several devices were supplied with it. It was released to manufacturers on May 11, 2009; the first devices running the operating system appeared in late October 2009. Several phones that officially shipped with Windows Mobile 6.1 can be officially updated to Windows Mobile 6.5. This update includes some significant new added features, such as a revamped GUI, a new Today screen resembling that of Microsoft's Zune player with vertically scrollable labels (called 'Titanium'). WM6.5 also includes the new Internet Explorer Mobile 6 browser, with improved interface.

Along with Windows Mobile 6.5, Microsoft announced several Cloud computing services codenamed "SkyBox", "SkyLine", "SkyMarket". "SkyBox" has been confirmed as My Phone, while "SkyMarket" has been confirmed as Windows Marketplace for Mobile. This version was designed mainly for easier finger usage. Some reviewers have noted interface inconsistencies, with some applications having small buttons making them harder to operate using only a finger. Whilst this version of Windows Mobile does not natively support capacitive screens, mobile manufacturers have been able to use them on their devices

In the months following this release, development shifted from Windows Mobile to its successor Windows Phone. As such no major upgrades were planned or released, although three minor updates; 6.5.1, 6.5.3 and 6.5.5; were made to satisfy consumers during the transition period. 6.5.1 brings larger user interface elements, including icon based soft buttons (rather than text based), an updated contacts app, native support for A-GPS, improved threaded text messaging, and performance improvements. It was unofficially ported to several Windows Mobile phones.

The second minor update was announced on February 2, 2010, along with the Sony Ericsson Aspen which was the first phone to use this version. 6.5.3 continues the trend of attempting to provide a more finger-friendly user interface with several new usability features such as native support for multitouch; although device maker HTC Corporation created proprietary work-arounds to allow multi-touch to work on some applications it installed on its HD2 handset(However, Microsoft applications on this handset, such as the Internet Explorer web browser, did not support multi-touch.) and drag-and-drop start menu icons. Touchable tiles replaced soft keys." Internet Explorer Mobile 6 has also received some major updates including decreased page load time, improved memory management and gesture smoothing. As with other updates it was unofficially ported to some other devices. Additional features include threaded email and Office Mobile 2010.

8.  Windows Mobile 7

Windows Phone 7 was the first and previous release of the Windows Phone mobile client operating system, released worldwide on October 21, 2010, and in the United States on November 8, 2010. An update to the OS codenamed Mango (also referred to as Windows Phone 7.5) was released in May 2011. In January 2013, Windows Phone 7.8 was released. It added a few features backported from Windows Phone 8, such as a more customizable start screen. It was succeeded by Windows Phone 8, which was released on October 29, 2012.

Microsoft officially unveiled the new operating system, Windows Phone 7 Series, at the Mobile World Congress in Barcelona on February 15, 2010, and revealed additional details at MIX 2010 on March 15, 2010. The final SDK was made available on September 16, 2010. HP later decided not to build devices for Windows Phone, citing that it wanted to focus on devices for its newly purchased webOS. As its original name was criticized for being too complex and "wordy", the name of the operating system was officially shortened to just Windows Phone 7 on April 2, 2010.

On October 11, 2010, Microsoft's CEO Steve Ballmer announced the 10 launch devices for Windows Phone 7, made by HTC, Dell, Samsung, and LG, with sales beginning on October 21, 2010 in Europe and Australia and November 8, 2010 in the United States. The devices were made available on 60 carriers in 30 countries, with additional devices to be launched in 2011.Upon the release of Windows Phone 7's "Mango" revision, additional manufacturers became partners, including Acer, Fujitsu, and ZTE.

Windows Phone initially supported twenty-five languages, with applications being available through Windows Phone Store in 35 countries and regions. Support for additional languages and regions were subsequently brought through both the Mango and Tango updates to the OS respectively.
