Hey guys, integrate SP2 into a copy of your WinXP CD, and then look at the unattend.txt file in the i386 folder, see a product key at the bottom? If so, post the first 5 digits here, I want to see if there's a bug here: Mine starts with : CD87T Does yours? If it's different, I suggest we test them on a virtual machine and post our results, see if the cd keys work Those of you with AUTHENTIC CD KEYS, see if it's the same as the CD Key you used, I know MINE isn't
