Windows XP (I have recently started as Final version) you can but in spite of bad experiences of some users describe as a milestone of the operating systems. Because a BS Anyway runs only as good as its user. I for one had since Win98 and WinME with never problems. The fact is now times that some Hardwarekonstelationen are so unfavorable that can happens to a Windows crash. With Win2k I was never satisfied (as gamers). But one must also not forget that it was not designed for it! But Windows XP Home & Prof. now combines a based on NT / 2000 core. That may be true only for such horror for gamers etc. But XP was with the multimedia capabilities of 98 / Me ausgestattet.Und I have to say run the games without problems and everything else also. After installation I have no driver inst. need except for the TV card. And crashes I had after 3 weeks now not even had !!! All in all, one has to honestly say: Hats off Microsoft !!!
