medimax, roel is totally correct, if windows (particularly XP) could run by itself it is a stable as ANY other op system, BUT because it has been around so long microsoft have to ensure backwards compatibility with thousands of programs (a lot of which have very dubious programming skills behind them) and it is THESE programs that cause windows to shut down...but this is not a PC forum so i will leave it there..believe me i could go on (as could roel i suspect ) but "time and place"...

peace, out
