I bought a Dell Reinstallation CD (still sealed) for Windows XP Professional x64 Edition from eBay. It looks legit but Inside the CD envelope there was a product key sticker that says "Windows XP Professional". The product key on the sticker is different than the one on Dell Reinstallation CD. Is this a pirated copy or mistake?
Its hard to say if it is. The product key would be different than the Dell win xp disk. It could be a retail version.
I just tried to change the product key using Microsoft's recommended steps but the one on sticker doesn't work. The part number for this is DP/N 0P949K.
My database does not show this part number.
