One PC upgraded from MS-DOS 5.0 to Windows 7, one version of Windows at a time

As they generally say with whacko stunts, don't try this at home. Posted on March 2, this video shows a user upgrading the same computer (actually, a virtual machine) to every major Windows version.

He started with MS-DOS 5.0. We noticed that Windows Me, which was a highly criticized sequel to Windows 98, was omitted from the presentation. Probably a good choice, as it was known to be one of the worst WIndows versions (although some people would like to label Windows Vista similarly).

Take a look, below.
