Microsoft Windows is the name of several families of computer software operating systems created by Microsoft. Microsoft first introduced an operating environment named Windows in November 1985 as an add-on to MS-DOS in response to the growing interest in graphical user interfaces (GUIs).

All versions of Microsoft Windows are commercial proprietary software.

={{anchor|GI-CE}}Windows Embedded Compact=

Windows Embedded Compact (Windows CE) is a discontinued variation of Microsoft's Windows operating system for minimalistic computers and embedded systems. Windows CE was a distinctly different kernel, rather than a trimmed-down version of desktop Windows. It is supported on Intel x86 and is compatible on MIPS, ARM, and Hitachi SuperH processors.

9.0c (Oct 2006) (optional)

It is possible to install the MS-DOS variants 7.0 and 7.1 without the graphics user interface of Windows. If an independent installation of both, DOS and Windows is desired, DOS ought to be installed prior to Windows, at the start of a small partition. The system must be transferred by the (dangerous) "SYSTEM" DOS-command, while the other files constituting DOS can simply be copied (the files located in the DOS-root and the entire COMMAND directory). Such a stand-alone installation of MS-DOS 8 is not possible, as it is designed to work as real mode for Windows Me and nothing else.

={{Anchor|TI-NT}}Windows NT=

The Windows NT kernel powers all recent Windows operating systems. It has run on IA-32, x64, DEC Alpha, MIPS architecture, PowerPC, Itanium, ARMv7, and ARM64 processors, but currently supported versions run on IA-32, x64, ARMv7, and ARM64.

Supported file systems

Various versions of Windows support various file systems, including:FAT12, FAT16, FAT32, HPFS, or NTFS, along with network file systems shared from other computers, and the ISO 9660 and UDF file systems used for CDs, DVDs, and other optical disc drives such as Blu-ray. Each file system is usually limited in application to certain media, for example CDs must use ISO 9660 or UDF, and as of Windows Vista, NTFS is the only file system which the operating system can be installed on. Windows Embedded CE 6.0, Windows Vista Service Pack 1, and Windows Server 2008 onwards support exFAT, a file system more suitable for USB flash drives.

Hardware requirements

Installing Windows requires an internal or external optical drive, or a USB flash drive. A keyboard and mouse are the recommended input devices, though some versions support a touchscreen. For operating systems prior to Vista, an optical drive must be capable of reading CD media, while in Windows Vista onwards, such a drive must be DVD-compatible. The drive may be detached after installing Windows.
