Windows is a family of operating systems developed by Microsoft. Originally a graphical add-on for Microsoft DOS, Windows is now the dominant family of operating systems on the desktop.
Today there are several branches of Windows:
- Windows for desktops, notebooks, netbooks, and tablets
- Windows Server, for servers
- Windows Embedded Compact, for embedded devices
- Windows Phone, for smartphones
If your question is version-specific, do not use the windows tag; instead use an appropriate version-specific tag, such as windows-7, windows-xp, or windows-server-2008-r2.
