Windows XP was the best in my experience. Especially with Service Pack 2. Didn’t have a single system crash with XP.
Agreed. I still have XP on a hard drive that I can reinstall in my desktop if I wanted to.
I still have XP on an old desktop that I keep around because I use some ancient (late 90s) software that supports an equally ancient and expensive piece of hardware, and it will only run on a real XP system (no emulations will work).
Every time I fire it up, I am reminded of how good XP was.
