Gotcha. I simply Googled "checking product key" and got quite a few
hits. From:

This worked for me (recommended for a Dell laptop, I have a Vaio):
1) Please go into the CMD prompt (Start/Run --> cmd.exe )
2) Then type cd /d %windir%\inf and make sure we are in that
directory.
3) Then type ren oem*.inf oem*.old, it will go back to the prompt
after giving you some error (Do not worry about it)
4) Then type ren oem*.pnf oem*.old1, it will go back to the prompt
after giving you some error (Do not worry about it)
5) Then goto start - run - type "%windir%\inf" and you will see
the files in the folder.
6) Then find the file by name INFCACHE.1 and take a backup of it
to desktop (by copying it to desktop) and delete the INFCACHE.1
from c:\windows\inf.
7) Close all windows and reboot the computer to safe mode and
start the installation of SP2 and it should go fine.
(and be sure to press Enter after typing *each* command)
