Microsoft Windows 1.01 (1.xx/1.xy) - 1985-09-03 - CompuData
Compiled on/around 1985-09-03, modified with keyboard-drivers by CompuData on 1985-09-23 and an updated setup.exe (1.xy from 1985-09-30, 1.xx seems to be from 1985-09-25 instead).
The apps (from late Aug/early Sep 1985) were already branded as "1.01", the bootscreen is branded as "1.xx". When you really looking/digging into the apps you can find changes compared with Premiere Edition and the Final Edition.
Note: Disc 1 contains a "Write.DAT" file, but CompuData didn't shipped it with Write.exe, their documentation explicit stated you got "Windows Write" with/after the Update Toolkit (see below)
