Related to my older question:

Get xp product key from boot

Thanks for the help on that one.

So, in the end, i couldn't get into my harddrive because i didn't have the available hardware to hook it up to another computer to get the old activation key. So, instead, i entered another activation key (i know, naughty) in hopes that there would be a way to retrieve the old one, restore point or something afterwords.

What legal ways can I get xp re-activated after a repair when I don't have any record of my activation key?

for those who think im just trying to crack it, your wrong:

1. Got a virus, which stopped me from getting into windows
2. Got AVG Anti Virus, which stopped me from getting into safe mode
3. Got a 2 year old, who decided to rip-off and chew my activation sticker on my computer (nice one).
4. Repaired windows installation thinking i wouldn't be asked to re-enter the activation key, to find that i was.
