Have just had a problem with activating my 'GENUINE' Xp disk(Because it is a OEM disk) and apparently can only be used X number of times???to activate windows.
Anyway, for information purposes, Microsoft themselves hava a small prog' for this very problem. Called: 'Microsoft XP Key Changer' I found it on a site 'Demonoid' which is a 'Torrent' site. D/L and used it and now all is ok for my Windows.
Demonoid is a registrable site needing a code to register!!
Hope this helps someone on SubSim!!
