I'll be the first to say the unpopular take on HN: I don't think Windows 95 looks that good (compared to today). I personally find more modern (like MacOS 10) styles to look the best, and flat designs to be just as usable as more skeumorphic ones. It seems to me that preference for UI styles is completely personal, probably being influenced by what OS we initially used. As someone (potentially a lot) younger than man…
* 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.
