Being at the right age when Windows 95 came out, I didn't really know that there was a "Windows" prior to 95. My dad's computer ran DOS and used something called Powermenu as an organiser for executing programs. I think I had to run Wolfenstein in a tiny window for it to be fast enough to be playable, and may have, at one point, deleted one of the required DOS system files in order to try to tweak the life out of it to try to get it playable full screen. I think that was a 286. More years ago than I care to admit.
