Ok, I read the article. So it won't work because wpa.dbl also contains a serial based on the partition and if you format it, it doesn't match. I got my laptop preinstalled, so it's probably oem, allthough there wasn't any other software on it but drivers. I do not have a cd or recovery partition. So what I did is I downloaded xp home and formatted and installed, then activated using the internet. So is it still oem now, or does it change to normal? Can I back up this activation or do I need to use dos programs to check the partition serial like in the artical?
