Windows 1.0 1985-10-28 build

Windows 1.01 1985-10-28 build is a late pre-release build of Windows 1.0. BetaArchive member trueyanksfan posted alleged Premiere Edition disk scans on 2014-03-16. A few months later, on 2014-09-12, he posted an update, revealing disks 1-3 were overwritten with other data and only disk 4 survived. He also posted a screenshot showing that the dates of the files are near the end of 1985-10.

The disks have since been sold on eBay. It was later confirmed that the remaining files on disks 3 and 4 are from a later build from around late 1985-10.
