A "personal computer" version of Windows is considered to be a version that end-users or OEMs can install on personal computers, including desktop computers, laptops, and workstations.
The first five versions of Windows–Windows 1.0, Windows 2.0, Windows 2.1, Windows 3.0, and Windows 3.1–were all based on MS-DOS, and were aimed at both consumers and businesses. However, Windows 3.1 had two separate successors, splitting the Windows line in two: the consumer-focused "Windows 9x" line, consisting of Windows 95, Windows 98, and Windows Me; and the professional Windows NT line, comprising Windows NT 3.1, Windows NT 3.5, Windows NT 3.51, Windows NT 4.0, and Windows 2000. These two lines were reunited into a single line with the NT-based Windows XP; this Windows release succeeded both Windows Me and Windows 2000 and had separate editions for consumer and professional use. Since Windows XP, multiple further versions of Windows have been released, the most recent of which is Windows 11.
