Windows 1.0 Premiere Edition

Windows 1.0 Premiere Edition is a pre-release version of Microsoft Windows 1.0. It was originally sent to key players in the computer industry by Microsoft to prove that their product wasn't vaporware. Before releasing the official version, Windows 1.01, the memory management code had to be completely rewritten; this would be the key difference between Premiere and 1.01.

A build was leaked in 2008 purporting to be the Premiere Edition. The 2008 build still remains available on several websites, but it is a known fake. In 2014-03, BetaArchive user trueyanksfan claimed to have the real floppies, and also posted a photo of them. On 2014-12-18, a set of disk images from the real Premiere Edition was released by the BetaArchive user Alias, through mrpijey.
