I have WinXP Home installed on my main computer. I am

registration and then upgrade the main computer to WinXP
Pro?
Not really, because you are in essence using the WinXP Home license
twice:
Once on the new second new computer, and also on the original computer
where it forms part of the license for using the Windows XP Pro
Upgrade.
When you install an upgrade version of an operating system or
application program then it requires the presence of a valid license
for a previous version of that operating system or application so as
to justify the use of the upgrade version. Those two licenses - the
one for the upgrade and the one for the version being upgraded from -
are effectively merged to provide the combined license for the new
version.
However if you are installing an OEM version of XP Pro or a Retail
Full Install (double the price of the Retail Upgrade) then you can use
the XP Home on another computer *unless* the XP Home is an OEM
version.
OEM versions are permanently locked to the first computer they are
installed on and cannot be legitimately transferred to another
computer under any circumstances.
Good luck
