I have purchased a new PC & want to update Windows XP Home (OEM) to XP
Professional. I have a legal copy of XP Home (full version)
& XP Professional Update both with product key numbers.
By "XP Professional Update" are we to understand that you have a retail
WinXP Pro Upgrade license and CD?
I have only attempted to update the OEM ver. of Home that came on the PC,
using the XP Professional Update Product Key f rom the update I purchased -
but I keep getting a message saying the Product Key is invalid.
You need to examine the Product Key very carefully. It's awfully
easy to mistake a "B" for an "8," a "G" for a "6," an "S" for a "5," or
a "Q" for a "0" or "O." Fortunately, Microsoft had the good sense to
leave the "1's," "I's," "O's," and "0's" out of the equation. Also, be
sure that your <CapsLock> is _off_ while entering the Product Key --
this isn't supposed to make a difference, but I've seen it do so, on
rare occasions.

I have used the update on my old PC.
Has it subsequently been removed from that old PC? Only then can the
Upgrade license be installed elsewhere.
1) Should I install my purchased ver of XP Home over the OEM ver. OR
There would be no need to do so, nor would any benefit accrue from such
a course.
2) How do I get the XP Professional ver I have to work?
Verify that you're entering the correct Product Key. Alternatively,
you could use the Upgrade CD to perform a clean installation, after
having backed up any important data.
Simply boot from the WinXP Upgrade CD. You'll be offered the
opportunity to delete, create, and format partitions as part of the
installation process. The Upgrade CD checks to see if a qualifying OS
is installed, and, if it finds none, it asks you to insert the
installation media (CD) of that OS. Unfortunately, an OEM
"Recovery/Restore" CD will not work for this purpose; you must have a
true installation CD, complete with the "\Win98" folder and *.cab
files, or the "\i386" folder of WinNT/2K.
