Here’s one for the computer nerds amongst our readers. Andy of Andy’s Tech Experiments Blog decided to install every version of Windows on a computer to see how easily he could upgrade through them all – from MS-DOS Shell all the way to Windows 7! It’s pretty neat to see every version of Windows lined up side to side. Ahhh, it brings me back. I love how he uses Doom 2 and Monkey Island to test compatibility, but the best part is that (spoiler alert) Reversi manages to stay on the computer from its install all the way until Windows 7. Crazy!
