Windows XP
When Windows XP first released, people criticized it for having a theme that they hadn’t seen before in Windows. People thought it was very kiddish and appealing to children, not being taken as seriously for the large userbase of the time. There were also criticisms about how fragile Internet Explorer was (I’m not kidding, I was there and Internet Explorer back then was at its most insufferable.).
But these days, just because of how bad Windows 8, 8.1, 10 and now 11 have been, people have praised Windows XP so much.
Well, different than today you could just select classic style somewhere and it looked like the improved cross between W95 and NT, while today I’m stuck with the abysmal W11 interface.
I can’t say much about the browser though, as I am old netscape gang that soon increasingly switched to Phoenix (that’s what later became Firefox).
Basically wasn’t that much of an issue if you knew your way around.
XP crashed more often than newer Releases, though (but still much less than W95).
