No, that's not correct. Please don't confuse a CPU and a
computer. Your laptop and your desktop are computers, not CPUs.

A "CPU" is a chip, the "brain" of the computer. Examples of CPUs
are Pentium, Pentium II, Pentium III, Pentium IV, Celeron,
Athlon.

It has nothing to do with OEM copies of Windows XP in particular.
All copies of Windows XP *Professional* (but not Home) can
support up to two CPUs on the same computer. XP Home can support
only a single CPU.

That's the technical issue. The licensing issue is that not only
Windows XP, but all versions of Windows since Windows 3.1 are
licensed to be run on a single computer. You can not legally
install a single copy on two computers.
