Windows 1.0 InfoWorld 1985-07-01 build

The Windows 1.0 InfoWorld 1985-07-01 build is a pre-release build of Windows 1.0 shown in the 1 July 1985 issue of InfoWorld. It closely resembles the May Beta, but the MS-DOS Executive still displays free disk space remaining above the file list like the Alpha Release (most of it is covered up by the Special menu, though). The Clock icon is slightly different as well, and the new Calculator has two "M-" buttons instead of an "MC" button at the top and "M-" at the bottom.
