The Windows Upgrade Path: Windows 1 to Windows 7

Andrew Tait decided to see if an install of Microsoft’s original Windows, could be upgraded through each version to end up at the current version. ┬áIts amazing that yes it worked, and that Windows 3 programs continued to work in Windows 7.

Perhaps even more remarkable, is that Windows 1 was deigned to run on an 8086 processor, clocked at 4.77MHz with 256k of RAM. Using VM Ware it can still be run on modern hardware.

A parting thought…The entire Windows 1 OS will fit in the L2 cache of any modern processor.
