This lot offers an original sealed software package published by Microsoft in 1991, containing Microsoft Windows version 3.0 together with MS-DOS 5.0. The set is supplied on 3.5-inch floppy disks and includes manuals and printed documentation inside the box. This release was issued as a combined package, providing users with both the Windows graphical environment and the MS-DOS operating system. It offered improved memory management, enhanced disk utilities, and compatibility with a wide range of DOS and Windows-based applications. The outer box remains factory sealed in its original shrink wrap. The sides display the Microsoft logo and an authenticity hologram, while the rear shows the full system requirements for IBM-compatible PCs of the early 1990s. The back of the package is also clearly marked “Not for resale, except with a computer system.” Publisher: Microsoft Corporation, 1991. Condition as seen in the photos, offered unopened in its original packaging.
