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 March 16, 2014. A few months later, on September 12, 2014, 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 October 1985.

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 October 1985.
