Windows 3.1 build 050

Windows 3.1.050 is discussed in internal Microsoft e-mails from late 1991-09.

The e-mails mainly discuss application compatibility with Windows 3.1 Beta 2, though this particular build is mentioned in relation to SmartDrive (codenamed Bambi) as "Other critical work".

It was also mentioned in the same e-mails that the development team planned on putting code in place that would make sure Windows 3.1 would only run on MS-DOS, since only MS-DOS and IBM DOS were officially supported. This suggests the AARD code was put into place sometime after Beta 2.
