Windows 1.0 is the first version of Microsoft Windows that was released to the public.
While Windows itself was in development since at least as early as 1983, not only was it known as "Interface Manager", but it also used the version number 0.9, and as such, while the project was continued, not only was it renamed to Windows, but it was to be released under the version number 1.0, rather than 0.9. Several pre-release versions were released, such as Development Release 1, Development Release 2, Development Release 3, Development Release 4, Development Release 5, Alpha, and Beta.
A final preliminary release, Premiere Edition (1.00), was compiled on 17th August 1985, and subsequently released to a limited number of people (along with a later compile from August 20th that year, with some slight updates), and 1.01, released on November 20th, 1985, was the first version of Windows to be released to general availability (it was called Windows 1.01 to differentiate it from Windows Premiere Edition), whereas several more versions, Windows 1.02 and Windows 1.03, were released, as per smaller updates made to the code, with the latest version, 1.04, being released in April 1987.
Windows 1.0 was not widely successful, and was quite understandably pronounced as a "flop" by some people, though it was the start of Microsoft's entrance into the then growing graphical user interface-based operating system market.
Several copies in other languages, such as Windows 1.03 in German and French (and a hard drive image of Windows 1.03 Japanese for the PC-98), as well as certain OEM releases, such as a Zenith OEM release of Windows 1.01, and Olivetti and Siemens OEM releases of Windows 1.03, are known to exist.
