My computer was stolen.
The ISP can not tell me the MAC address so the only way I can think of to identify the computer as mine (personal data was wiped) is through the Product Id for Windows. (I doubt the theif was smart enough to install a new copy of Windows.)
I have the CD Key of the copy (XP Home) I installed, but I did not write down the PID.
How do I re-generate the PID from the CD Key?
