New to the site. So, I have an aspire laptop which is currently running win mce. I can't run a certain audio program because of this os. I am wondering if there is a way to revert to the pro or home version without any conflicts. I have backed up all the files I wish to keep so starting from scratch isn't a problem. Any ideas? I have my key from the mce as well and am also wondering if that key would possibly work on the xp disc I have. Maybe? Yes? No?
