Windows 1.xx

Windows 1.xx is a pre-release build of Windows 1.0 shipped by CompuData (later renamed to Tulip Computers) in early fall of 1985 with their first iteration of the Tulip System PC Compact and Advance/Extend. It is thus also one of the earliest OEM releases of Windows 1.0. It was found by ultrawindows and uploaded to BetaArchive on 2 March 2019.https://www.betaarchive.com/forum/viewtopic.php?t=39521
==Overview==
The base of this build was compiled around 3 September 1985, CompuData added additional keyboard layouts around 23 September 1985, and later updated SETUP.EXE (setup version 1.xx is probably from 25 September 1985, while version 1.xy is probably from 30 September 1985). It is unclear if setup version 1.xx was also released before it was updated to 1.xy soon after, but since the Windows Upgrade Kit to version TC 1.00 (from February 1986) explicitly mentions "Windows SETUP, version 1.xx (or 1.xy)", it can be assumed it was.
The included applications are from late August 1985 and early September 1985, and are already branded as "version 1.01" in the About box, though the floppy disk labels say "APPLICATION version 1.xx". 
The origin of the "1.xx" and "1.xy" designations is rooted in the fact that there was no final version of Windows available when Compudata released their new machines. To address this, they adopted these temporary designations. The Windows Upgrade Kit to version TC 1.00 says the following about this designation:
Although this build contains a WRITE.DAT file on the first disk and setup will ask for the Write disk at the end, CompuData apparently didn't include it with this build. Windows Write was instead included as part of the upgrade to version TC 1.00, which creates an entirely new Write disk.
This build features a unique font, similar to the VGA font used in Windows 2.x. Several applications have been updated since Premiere Edition, and it's now no longer possible to minimize MS-DOS Executive if no other applications are running.
Disk 1 contains two unrecoverable deleted keyboard drivers (KEYBDA.DRV and KEYBNO.DRV), but it is possible to get these files by upgrading to the TC-1.00 release.
==Different floppy sets ==
The disk set released in September 1985, branded with the CompuData logo, was uploaded to BetaArchive. It included a comprehensive user guide featuring numerous screenshots from 2 earlier builds, likely dated around June 1985. A subsequent version of the set, released in January 1986 with identical part numbers, bore the Tulip Computer logo instead. This later release also featured a slightly updated user guide, primarily reflecting changes such as replacing "Compudata" with "Tulip Computers" in the text (and images).
