Comparison of Microsoft Windows versions
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).

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

The MS-DOS variants 7.0 and 7.1 can be separated from Windows to small partition on a new harddrive, if a second operative system is wanted or in order to run old programmes. If someone wants to, or is in need of, a DOS system together with of Windows, then DOS ought to be installed prior to the Windows installation, in the beginning of a small partition of a hard disk. The system must be transferred by the (dangerous) "SYSTEM" DOS-command. While other required files just can be copied. They are those files which are located in the DOS-root and the entire COMMAND directory. But as all DOS files are tiny or small compared to many modern Windows files, one may copy them all just as well. MS-DOS 8, cannot be used as a second or third operative system, as it's designed to work as real mode for Windows Me and nothing else.
Windows NT
The Windows NT kernel powers all recent Windows operating systems. It runs on IA-32, x64 and Itanium processors.

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 discs 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 flash drives.

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