Windows 1.0 Personal Computer News 1983-12-01 build

Windows 1.0 "PC Mag" build is a very early pre-release build of Windows 1.0, originally shown in the 1984-01-24 issue of PC Mag. The photo is of somewhat poor quality, though the observable UI details suggest this build is likely earlier than the one shown at Fall COMDEX 1983, and possibly related to the build shown in the third photo in the 1983-11-21 issue of Infoworld.

The same photo was also featured in the 1983-12 issue of Personal Computer News, 1984-01 issue of Data Processing, 1984-02 issues of Creative Computing and Practical Computing , and the 1984-04 issue of InfoWorld.
