Yo... I got one I'm not sure if other people are running across... I have one PC in my house that gets seriously effed whenever I use the Loader on it... Most recently, after upgrading an unauthorized Vista machine to a win 7 machine. After upgrade, I ran the loader, and the machine wouldn't boot, or at least appeared that way. In the past, this has happened to me when installing Vista and using the Loader on said machine. In the past, no fix, not even system restore, would bring it back, I would have to re-install. This time, restoring back to the upgrade fixed the boot issue, and get this.. the machine is activated!? Anyway, all is well, and I ain't bitching about awesome software that lets me get free s**t, I just thought you might want to know. This is on an AMD 64 3800+ (single core) based HP Pavilion. Also, I'm thinking that maybe I've been selecting a brand option (you know where you can pick dell, hp, whatever) willy-nilly... does that have an impact, i.e., if it's wrong, is that bad? LOL. Thanks bro. Windows 7 is great and is even better once unlocked!
