Windows Mobile is a discontinued family of mobile operating systems developed by Microsoft for smartphones and personal digital assistants. It was renamed “Windows Mobile” in , at which point it came in several versions similar to the desktop versions of Windows and was aimed at business and enterprise consumers.

Following the rise of newer smartphone OSs iOS and Android Windows Mobile never equalled the success and faded rapidly in the following years. By February , Microsoft announced Windows Phone to supersede Windows Mobile with a more modern take on the industry. As a result, Windows Mobile has been deprecated. Windows Phone is incompatible with Windows Mobile devices and software.

Most versions of Windows Mobile have a standard set of features, such as multitasking and the ability to navigate a file system similar to that of Windows 9x and Windows NT , including support for many of the same file types. Similarly to its desktop counterpart , it comes bundled with a set of applications that perform basic tasks. Internet Explorer Mobile is the default web browser , and Windows Media Player is the default media player used for playing digital media.

The mobile version of Microsoft Office is the default office suite. Internet Connection Sharing , supported on compatible devices, allows the phone to share its Internet connection with computers via USB and Bluetooth. Most devices with mobile connectivity also have a Radio Interface Layer. The Radio Interface Layer provides the system interface between the Cell Core layer within the Windows Mobile OS and the radio protocol stack used by the wireless modem hardware. This allows OEMs to integrate a variety of modems into their equipment.

The user interface changed dramatically between versions, only retaining similar functionality. The Today Screen , later called the Home Screen , shows the current date , owner information, upcoming appointments, e-mails, and tasks. The taskbar displays the current time as well as the volume level. Devices with a cellular radio also show the signal strength on said taskbar.

It includes 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. It allowed third party developers to 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. 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. Microsoft’s work on handheld portable devices began with research projects in , with the work on Windows CE beginning in It is treating pens right for the first time.

The two disbanded groups would form the Pegasus project in Under the name Handheld PC , a hardware reference guide was created and devices began shipping in , although most of these device bore little resemblance to the goal of a pen-based touchscreen handheld device.

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. It retained backwards compatibility with such Palm-size PC applications.

While, several Pocket PC phones were released, Microsoft’s smartphone hardware platform was not yet created. Infrared IR File beaming capability was among the original hardware features. Crucially, unlike the interface on predecessing Palm-size PC, the Pocket PC had a less cluttered interface more suitable for a mobile device. This initial release had multiple built-in applications, [12] many of them similarly branded to match their desktop counterparts; such as Microsoft Reader , Microsoft Money , Pocket Internet Explorer and Windows Media Player.

Notes, a note-taking app saw its first release and would be supported by most later versions of Windows Mobile. Intelligent character recognition support allowed Notes to distinguish styles of handwriting to be learned by the OS during processing to improve accuracy and recognition levels. 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.

Newly added or updated programs include [14] [15] [16] [17] 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. The last was designed especially for Pocket PCs which include phone functionalities. Windows Mobile was powered by Windows CE 4. 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. A puzzle game titled Jawbreaker is among the preinstalled programs.

GAPI was included with this release to facilitate the development of games for the platform. 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. Windows Mobile 5. Microsoft offered mainstream support for Windows Mobile 5 through October 12, , and extended support through October 13, It used the.

NET Compact Framework 1. Other features included an enhanced battery-saving capability called persistent storage capability. 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. 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. Improvements were made to ActiveSync 4. 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.

This release was the first to include DirectDraw with hardware acceleration, replacing the deprecated graphics component of GAPI. Windows Mobile 6 is powered by Windows CE 5. Functionally, it works much like Windows Mobile 5, but with much better stability. Along with the announcement of Office Mobile 6. In addition to the newly included programs with Office Mobile improvements were made to existing applications.

A large number of Windows Mobile users are enterprise users business environments were targeted. To aid development for programmers,.

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. Windows Mobile 6. 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. Domain Enroll is functionality to connect the device to System Center Mobile Device Manager , a product to manage mobile devices.

Aside from the visual and feature distinctions, the underlying CE versions can be used to differentiate WM 6. In WM 6. 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 Along with Windows Mobile 6.

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. The second minor update was announced on February 2, , along with the Sony Ericsson Aspen which was the first phone to use this version.

Touchable tiles replaced soft keys. Additional features include threaded email and Office Mobile The last minor update and the last released version is 6. It first leaked in January , and was unofficially ported to some Windows Mobile phones. Although Microsoft released a similarly-named Windows 10 Mobile in , this operating system is unrelated to the former Windows Mobile operating systems.

There are three main versions of Windows Mobile for various hardware devices: [65]. Windows Mobile for Automotive and Windows Mobile software for Portable Media Centers are among some specialty versions of the platform. Microsoft had over 50 handset partners, [66] when Windows Mobile was still being shipped on new devices. The operating system has compatibility with Windows Mobile 6. Pocket PCs and personal digital assistants were originally the intended platform for Windows Mobile.

These were grouped into two main categories: devices that lacked mobile phone capabilities, and those that included it. Beginning with version 6 devices with this functionality ran “Windows Mobile 6 Professional” and those that lacked it ran “Windows Mobile 6 Classic”. Microsoft had described these devices as “a handheld device that enables you to store and retrieve e-mail, contacts, appointments, play multimedia files, games, exchange text messages with MSN Messenger, browse the Web, and more”.

Although in the broad sense of the term “Smartphone”, both Pocket PC phones and Microsoft branded Smartphones each fit into this category. Microsoft’s use of the term “Smartphone” includes only more specific hardware devices that differ from Pocket PC phones.

Windows Server key

Mainstream support ended on April 12, Extended support ended on April 12, [11] [12]. Windows Server is the second version of Windows Server operating system produced by Microsoft. It is part of the Windows NT family of operating systems and was released on April 24, An updated version , Windows Server R2, was released to manufacturing on December 6, Windows Server is based on the consumer operating system, Windows XP. Windows Server is the follow-up to Windows Server, incorporating compatibility and other features from Windows XP.

Unlike Windows , Windows Server ‘s default installation has none of the server components enabled, to reduce the attack surface of new machines. Windows Server includes compatibility modes to allow older applications to run with greater stability.

It was made more compatible with Windows NT 4. Windows Server brought in enhanced Active Directory compatibility and better deployment support to ease the transition from Windows NT 4.

Windows Server is the first server edition of Windows to support the IA64 and x64 architectures. The product went through several name changes during the course of development. When first announced in , it was known by its codename “Whistler Server”; it was named “Windows Server” for a brief time in mid, followed by “Windows. NET Server” and “Windows. NET Server “. After Microsoft chose to focus the “.

NET” branding on the. Windows Server was the first Microsoft Windows version which was thoroughly subjected to semi-automated testing for bugs with a software system called PREfast [17] developed by computer scientist Amitabh Srivastava at Microsoft Research.

Microsoft co-founder Bill Gates stated that Windows Server was Microsoft’s “most rigorously tested software to date. Microsoft used Windows Server ‘s kernel in the development of Windows Vista. Windows Server comes in a number of editions, each targeted towards a particular size and type of business. NET technology. Domain controller and Terminal Services functionality are not included on Web Edition. However, Remote Desktop for Administration is available.

Only 10 concurrent file-sharing connections are allowed at any moment. NET Framework version 2. When using it for storage or as a back-end with another remote server as the front-end, CALs may still be required. Microsoft Windows Server Standard is aimed towards small to medium-sized businesses. Standard Edition supports file and printer sharing, offers secure Internet connectivity, and allows centralized desktop application deployment.

A specialized variant for the x64 architecture was released in April Windows Server Enterprise is aimed towards medium to large businesses. It also provides the ability to hot-add supported hardware. Windows Server Enterprise is also the required edition to issue custom certificate templates.

Windows Server Datacenter is designed [25] for infrastructures demanding high security and reliability. Windows Server is available for IA, Itanium, and x64 processors.

It supports a maximum of 32 physical processors on IA platform or 64 physical processors on x64 and IA hardware. The Datacenter edition, like the Enterprise edition, supports 8-node clustering. Clustering increases availability and fault tolerance of server installations by distributing and replicating the service among many servers. This edition supports clustering with each cluster having its own dedicated storage, or with all cluster nodes connected to a common SAN.

Windows Compute Cluster Server CCS , released in June , is designed for high-end applications that require high performance computing clusters. It is designed to be deployed on numerous computers to be clustered together to achieve supercomputing speeds. Each Compute Cluster Server network comprises at least one controlling head node and subordinate processing nodes that carry out most of the work.

It ties nodes together with a powerful inter-process communication mechanism which can be complex because of communications between hundreds or even thousands of processors working in parallel. The application programming interface consists of over functions. A job launcher enables users to execute jobs to be executed in the computing cluster.

Windows Storage Server , a part of the Windows Server series, is a specialized server operating system for network-attached storage NAS. Launched in at Storage Decisions in Chicago, it is optimized for use in file and print sharing and also in storage area network SAN scenarios. It is only available through Original equipment manufacturers OEMs.

Windows Storage Server NAS equipment can be headless , which means that they are without any monitors, keyboards or mice, and are administered remotely. Such devices are plugged into any existing IP network and the storage capacity is available to all users. Multiple such NAS servers can be clustered to appear as a single device, which allows responsibility for serving clients to be shared in such a way that if one server fails then other servers can take over often termed a failover which also improves fault-tolerance.

Windows Storage Server can also be used to create a Storage Area Network , in which the data is transferred in terms of chunks rather than files, thus providing more granularity to the data that can be transferred. This provides higher performance to database and transaction processing applications. Single instance storage SIS scans storage volumes for duplicate files, and moves the duplicate files to the common SIS store.

The file on the volume is replaced with a link to the file. Windows Storage Server R2 provides an index-based, full-text search based on the indexing engine already built into Windows server. Windows Storage Server can be promoted to function as a domain controller; however, this edition is not licensed to run directory services. It can be joined to an existing domain as a member server. Windows Small Business Server SBS is a software suite which includes Windows Server and additional technologies aimed at providing a small business with a complete technology solution.

SBS has the following design limitations, mainly affecting Active Directory: [30]. Windows Home Server was announced on January 7, , at the Consumer Electronics Show by Bill Gates and is intended to be a solution for homes with multiple connected PCs to offer file sharing, automated backups, and remote access.

Intended use was for building firewall, VPN caching servers and similar appliances. Availability of the original version ended May 28, Availability of R2 ended March 5, End of extended support was July 14, all variants except Storage Server [9] , and End of Licence was May 28, R2 and original. All variants continued to receive Critical security updates until the end of extended support: [37].

While many features of the bit variant of Windows XP were brought over into Windows XP Professional x64 Edition, other limitations imposed by constraints such as only supporting bit drivers, and support for bit programs being dropped led to incompatibilities with the bit Windows XP editions available. Among the improvements are many of the same updates that were provided to Windows XP users with Service Pack 2. Features that are added with Service Pack 1 include:.

A full list of updates is available in the Microsoft Knowledge Base. Service Pack 2 for Windows Server was released on March 13, This was followed by build , known as Beta 2 Refresh. The final build is Microsoft has described Service Pack 2 as a “standard” service pack release containing previously released security updates, hotfixes, and reliability and performance improvements.

Service Pack 2 also adds Windows Server Scalable Networking Pack SNP , [48] which allows hardware acceleration for processing network packets, thereby enabling faster throughput. Windows Server R2 is an updated release of Windows Server , which contains a copy of Windows Server SP1 on one CD and a host of optionally installed new features on another disc, similar to Microsoft Plus!

New features of Windows Server R2 include: [51]. On July 13, , Windows Server ‘s mainstream support expired and the extended support phase began. During the extended support phase, Microsoft continued to provide security updates; however, free technical support, warranty claims, and design changes are no longer being offered.

Although Windows Server is unsupported, Microsoft released an emergency security patch in May for the OS as well as other unsupported versions of Windows including Windows Vista and Windows 7 RTM without a service pack , to address a vulnerability that was being leveraged by the WannaCry ransomware attack.

Anonymous users from managed to compile the Windows Server source code, as well as a Twitter user who posted videos of the process on YouTube proving that the code was genuine, [57] but was removed from the platform on copyright grounds by Microsoft.

The leak was incomplete as it was missing the Winlogon source code and some other components. Microsoft issued a statement stating that it was investigating the leaks.
