My brain believes two things simultaneously:

* that Windows 95 was the first GUI I used for any extended period of time and that I will naturally think it's the best one for this reason, for the same reason people tend to think things they liked when they were teenagers peaked when they were teenagers; and

* that Windows 95 really did rule - to repurpose Hoare, "not only an improvement on its predecessors but also on nearly all its successors"

...and those two could fight each other all day.

Taking off the rose-tinted glasses, I might miss the UI, but I definitely don't miss how unstable it was. 25 years on I can still rattle off a Windows 95 product key off the top of my head as a consequence of reinstalling it so often.
