I wasn’t there for XP but I was there for Win-95.
I actually started productivity with Windows 3.0, after using a couple of other OS’s that went by the wayside.
I did play around some with Win 1.0 and 2.0. They seemed to be just glorified menuing systems and too proprietary.
Myself, been using Windows since Version 2.0. I thought 3.11 Windows for Workstations was the cat's meow. Win95 was okay but I really liked Win98SE, still have a copy running in a VM....
