Various Windows 1.0 builds

On 11/08/2020, two collections of rare unleaked Windows 1.0 and MS-DOS application floppies were listed by BuySellTrade206 on Mercari. Unfortunately the buyer stayed anonymous and possibly chose not to share the contents of those floppies, thus all builds listed below are considered lost.
