Microsoft Windows is a series of graphical interface operating systems developed, marketed, and sold by Microsoft.
Microsoft introduced an operating environment named Windows on November 20, 1985.
Microsoft Windows came to dominate the world's personal computer market with over 90% market share, overtaking Mac OS, which had been introduced in 1984.
As of April 2014, the most recent versions of Windows for personal computers, smartphones, server computers and embedded devices are respectively Windows 8.1, Windows Phone 8.1, Windows Server 2012 R2 and Windows Embedded 8.

Windows 8.1 is a version of the Windows NT operating system and an upgrade for Windows 8.
First unveiled and released as a public beta in June 2013, it was released to manufacturing on August 27, 2013, and reached general availability on October 17, 2013, almost a year after the retail release of its predecessor.
Windows 8.1 added support for such emerging technologies as high resolution displays, 3D printing, Wi-Fi Direct, and Miracast streaming.
It can be installed on devices with as little as 1 GB of RAM and 16 GB of storage.
On July 1, 2014, Microsoft introduced a "pilot program" that would allow Windows 8 and RT 8 to be automatically updated to 8.1 through Windows Update.
The default search engine in Windows 8.1 is Bing.
End users are not restricted from installing other search engines or browsers.
New and changed features:
User interface and desktop
Apps
Online services and functionality
Security and hardware compatibility
Hardware functionality
User interface and desktop: The Start screen received several enhancements on 8.1, including an extended "All
Apps" view with sort modes (accessed by clicking a new down arrow button or swiping upward), small and extra-large sizes for tiles, and colored tiles for desktop program shortcuts.
The app snapping system has been extended; up to 4 apps can be snapped onto a single display depending on screen size, apps can be snapped to fill half the screen, and can also be used on any display in a multi-monitor configuration.
Apps can also launch other apps in a snapped view to display content; for example, the Mail app can open a photo attachment in a picture viewer snapped to another half of the screen.
The lock screen offers the ability to use a photo slideshow as its backdrop, and a shortcut to the Camera app by swiping up.
PC Settings was expanded to include options that were previously exclusive to the desktop Control Panel.
Windows Store was updated with an improved interface for browsing apps and automatic updates, the Mail app includes an updated interface.
The Camera app integrates Photosynth for creating panoramas, and additional editing tools were added to the Photos app.
Apps:
A number of additional stock apps were also added, including Calculator, Food and Drink, Health and Fitness, Sound Recorder.
Reading List (which can be used to collect and sync content from apps through OneDrive), Scan, and Help + Tips.
For Windows RT users, 8.1 also adds a version of Microsoft Outlook to the included Office 2013 RT suite.
Online services and functionality OneDrive (formerly SkyDrive)
The OneDrive app was updated to include a local file manager.
A Bing-based unified search system was added.
Searching for a music performer would return photos of the performer, a biography, and their available songs and albums on Xbox Music.
The messaging app from Windows 8 has been replaced by Skype, which also allows users to accept calls directly from the lock screen.
Windows 8.1 also includes Internet Explorer 11, which adds support for SPDY and WebGL, and expanded developer tools. The Metro-style version of IE 11 also adds tab syncing, the ability to open an unlimited number of tabs, and Reading List integration.
Security and hardware compatibility: On compatible hardware, Windows 8.1 also features a
transparent "device encryption" system based on BitLocker.
Encryption begins as soon as a user begins using the system.
Windows Store apps to use enrolled fingerprints as an authentication method.
A new kiosk mode known as "Assigned Access" was also added, allowing a device to be configured to use a single app in a restricted environment.
Windows Defender includes an intrusion detection system which can scan network activity for signs of malware. 8.1 also allows third-party VPN clients to automatically trigger connections.
Hardware functionality: Windows 8.1 adds support for 3D printing, pairing with
printers using NFC tags, Wi-Fi Direct, Miracast media streaming, tethering, and NVMe.
Windows 8.1 can scale text and GUI elements up to 200% (whereas Windows 8 supported only 150%) and set scaling settings independently on each display in multi-monitor configurations.
Market share: On the information gathered by Net Applications, adoption
rate in June 2014 for Windows 8.1 was at 6.61%, while the original Windows 8 was at 5.93%.
