Need your Microsoft product id but can’t find your original documentation?

We often need to know the product id but most of us never keep up with the original packaging which contains this vital number.

–Prior to XP:

Now, don’t go changing this number…

Navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

The number is listed under ProductId

Look but don’t touch.

–XP:

:( This recipe yields only the "registration #". The "key codes" is what is really needed. With previous Windows OS's this recipe would find those "key codes". With XP it doesn't.

If you can come up with a way to find them in XP, it would be appreciated.

John:

Thanks for pointing out AlexTheBeast's original error. I have corrected the recipe.

Several programs exist on the internet for finding the productID number for XP machines. I have linked to one in the recipe above. Download and run it on the machine in question and you'll have the productID in no time.
