How do I find my XP registration code?

[Familyman]

I've XP installed on three laptops and this PC. I want to reinstall my
Windows XP Profofessional but I do not have the registration code for
installation.

Is there any way I can find out the registration codes for Windows XP so I
can unstall it from this computer and install it instead on another
computer? Will this work? Can you see any problems in doing this?

If you're talking about the CD key that you used to install Windows, you can
recover that with RockXP¹. It's not free², but you don't have to pay for
it.
