Hi there
I have a number of Desktop PCs which were supplied with XP licences, however prior to delivery they were ‘downgraded’ to 2000Pro (at the time XP was very new and insecure).
I now need to upgrade these machines back to XP, however during the upgrade process when I enter the license key from the sticker on the PC itself I am told that it is invalid, and that the upgrade will stop.
Any ideas?
Cheers
Mark
