Want to rebuild existing XP Pro SP3 system. Unfortunately I lost track of the Windows key. Is there some way to extract it from the current install, before I wipe the disk? (I built the computer myself so I don’t have a sticker on the case.)

System Information for Windows or the Belarc Advisor will get that information for you.

Another good utility is NirSoft’s ProduKey – but note the Known Problems.
Also, Magic JellyBean KeyFinder is often suggested.Perhaps try all suggested utilities, to be sure?
(I did, and they all gave the same results – but of the Dell ‘master key’ originally used to install this and many thousands of other Dell PCs! This is different from the PC-specific one on the holographic sticker on the side of the case, which is the one that needs to be used if I have to do a reinstall. Beware that HP PCs may also exhibit this difference.
If you built the PC yourself, then no problem!)
