Well since it's 2021 allot of the people in the Windows 2k community made patches for the OS such as .Net Framework 4, Unofficial SP5, Visual C++ 2017, Windows Media Player 11. Modern browsers based on Chromium 54, Firefox 52.9 esr and up do their thing. Games like Portal 2, And the latest version of Minecraft (as of January 2021) work. KernelEX for 2000 was officially released almost a decade ago. And if i could i'd use it as a daily driver i wouldn't mind, however if i had to say what Windows 2000 was lacking compared to XP it would definitely be hardware support. Not allot of modern gpu's cpu's or motherboards support 2000 now a days and it kind of sucks because it definitely has potential.
