Currently using ME. Tried to upgrade to XP Home Edition, but right after the computer restart phase, got a STOP error. I suspect a non-working CD drive in the computer is responsible for that.
If I may make a suggestion..............
If you go XP, that’s cool. Great. Have fun.
But if you’re planning on upgrading to WinMe2, give linux a try sometime first. It won’t cost you a thing.
