Windows X.XX Emulator

Windows X.XX Emulator is a Windows family for operating system developers that were mainly developing Windows and writing the codes.

Development
During development of Windows 2000, Microsoft engineers planned to bring back MS-DOS mode for older titles like how Windows 98 runs on MS-DOS. By late 1999 Microsoft began development on this product known as "an operating system that includes other operating systems with it". But, this idea wasn't brought up during development the story was that Microsoft wanted to include just an emulation kernel on top of Windows 2000. Due, to high costs taking up disc space by a megabyte Microsoft scrapped that idea in 1996. As, follows during development of Microsoft Five Embedded in 1998, Microsoft noticed that Windows CE or (now known to merge with Windows Embedded) that they would be able to emulate any versions of Windows by using that specific .iso file to boot up. This idea which later had Microsoft to kill this operating system straight away. Basically this plan was being developed by Oracle since the 1990s.

Throughtout Windows Emulator's development it is considered one of the most released and patched operating system ever by using Developer builds instead of consumer builds.
