My Friend has a Dell PC which came with Windows XP Home Edition inc SP1a and CD to Reinstall if Necessary, The machine needed formatted and reinstalled so i knew my XP Home CD had SP2 included so i used it along with his Product Key and everything was fine, then i clicked on the 30 Day activation Keys bottom right hand corner and selected Already Registered, Just Activate but when i do this it prompts me that i need to change my Product Key, I phoned Microsoft who asked me had the gentleman changed any hardware etc and how many machines this product key had been used on and the answer is only 1, eventually they did something at their end to allow the product key to work but i don't want this hassle everytime i goto reformat his machine, Is there an easier way round this?
Many Thanks
