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.
