Windows 1.0 InfoWorld 1985-07-01 build

Windows 1.0 "InfoWorld 1985-07-01" build is a pre-release build of Windows 1.0 shown in the 1985-07-01 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.

This build may be related to Preliminary Version 0.50, although based on the way free disk space is displayed, it's more likely to be an earlier build.
