Hi. I have two computers, a Compaq used exclusively by my son (up until now) and a Dell used by me. The Compaq is (was) running Windows 2000 and the Dell Windows XP. Unknown to me my son used my Dell Windows XP re-install disc to install XP on his Compaq, which he then registered. I have just tried to refresh my own XP program and cannot register it, or open my computer beyond the Welcome screen without doing so.
It appears that whilst the program has loaded perfectly the disc is a "one shot deal" and cannot be used on two computers.
Is there any way I can remove this from my son's Compaq and re-use it on my Dell? If not, is there anything I can do without buying a new XP disc?
