I have an old computer and I want to install xp on it so I can get it running and then I want to donate it. The problem is when I installed xp x86 Home Edition, it wouldn't accept the key code on the label on the back of the box. It has been years since I installed or used xp so I've forgotten everything I used to know about getting xp to pass Microsoft's Genuine Validation. Any help would be appreciated. Thanks.
