PC (Microsoft Windows)

Virtual PC is a discontinued x86 emulator software for Microsoft Windows hosts and PowerPC-based Mac hosts. It was created by Connectix in 1997 and acquired by Microsoft in 2003, after which the program was renamed Microsoft Virtual PC. In July 2006, Microsoft released the Windows version free of charge. The Mac version was discontinued following the transition to Intel processors that same year.
In 2009, Microsoft released Windows Virtual PC, which is only compatible with Windows 7 hosts, and is the technical foundation for the latter's Windows XP Mode. Windows Virtual PC does not officially support MS-DOS or operating systems older than Windows XP Professional SP3 as guests. Virtual PC was discontinued in 2011 in favour of Hyper-V.
