It's my strong opinion that Windows 2000 Server, SP4 was the best desktop OS ever.

Source: I reviewed Cutler's lock-free data structure changes in Vista/Longhorn to find bugs in them, failed to find any.
I haven't yet gone more than a decade in the past before, so I can't promise forever, and GPU-accelerated things probably still break, but X11 is very compatible backwards.
Meanwhile, in 2025, with 64GB RAM and solid state drives, we hear, "Windows 11 Task Manager really, really shouldn't be eating up 15% of my CPU and take multiple seconds to fire up."
I meant to agree entirely with the parent comment by showing one specific way in which Win2K SP4 is far superior to Windows 11.
In Win2K, Task Manager takes less than a second to start on a 200 MHz, single core Pentium II with 64MB of RAM and a 5400 RPM IDE HDD.
