Windows Premiere edition

Windows Premiere edition, also known as Windows 1.1 internally, is an early version of Windows, infamous for its rarity in psychical form, its meant to show off what Microsoft was working on for their at the time upcoming Windows 1.01, which was the anticipated follow up to Windows 0.5. It had a very limited release initially in 1985, but was later bundled with certain PCs from 1986 to 1992 by accident in place of the regular Windows 1.01.
