From the "It ain't GPL, but it's better than a stick in the eye" department.
Now, what do the good folks at the FreeDOS project have to say about this?

Microsoft makes source code for MS-DOS and Word for Windows available to public
...
As part of this ongoing project, the museum will make available two of the most widely used software programs of the 1980’s, MS DOS 1.1 and 2.0 and Microsoft Word for Windows 1.1a, to help future generations of technologists better understand the roots of personal computing.

... But don't get too excited about the possibility of merging genuine MS-DOS code into FreeDOS. From the download page: "To access this material, you must agree to the terms of the license ... which permits only non-commercial use and does not give you the right to license it to third parties by posting copies elsewhere on the web." The website makes it very clear the "source and object code to Microsoft?s MS-DOS operating system versions 1.1 and 2.0" is for "non-commercial use" only. It's nice that Microsoft released the MS-DOS source code, but this is not "Free software."
