Windows 1.01 is the first update of Windows 1.0, also known as Microsoft Windows or simply Windows, the first iteration of the Windows product line by Microsoft.

Windows 1.0 was labeled the “Premiere Edition”. It was compiled on July 30, 1985, but wasn't for sale. It was released to reviewers and to retail outlets to demonstrate.

Windows 1.0 was a mouse-controlled graphic user interface rather than an operating system.

Versions

Windows 1.0, 1.01, the international-exclusive 1.02, 1.03, and the IBM PS/2 compatible 1.04 were restricted to the 16-bit architecture of DOS as they relied on the DOS operating system for essential functions.

Compatibility

Applications created with these versions were compatible with Windows 2 but weren't compatible with Windows 3 and higher operating systems due to the lack of protected mode.
