Windows 2000 was a pretty great OS. Used to enjoy using a Litestep shell instead of explorer. While it wasn't great for a lot of games, many did run fine. I liked it a lot better than OS/2 that I ran previously.
I generally ran 2-4x the amount of RAM as most did. Still do. Pretty sure this made a lot of the difference.
I rain it until it wouln't run sensible anymore in Windoes 10. I then ditched Windows for Linux soon after - I can recommend KDE Plasma if you want to have something thats sorta configureable enough like Litestep was.
windowblinds is a window decoration customizer - LiteStep does nothing of the sort :)
LiteStep completely replaces explorer.exe as the shell host and you can then customize what functions you want to have in your UI. The windows themself would stay looking the same.
