Trying to repair a PC using XP Pro CD and when typing in the licence key I am told that it is not valid !!
I have checked the sticker on the side of the PC and I have input the right characters, so I am now getting nowhere.
I have seen in the past a phone number to call Microsoft to get a new key after a system crash, but of course I do not have it to hand.
Can anyone help with a solution, or of course the phone number ???
