First, let me expand on a comment I made in my original post just so we are absolutely clear about what I did and what I want to do next.
In my OP, I said "Back in 2008 I apparently created a bootable XP install disk. ... Along with the date, I also wrote a Product Key on the disk"
That is not 100% accurate. What I actually did was create a bootable XP install disk and wrote only the date on it. In the same CD case I had another CD: An actual MS Windows XP Home Edition Upgrade Version 2002 CD. That is the disk that I had written the Product Key on sometime in the past. I don't know when I did that, but since the marker ink is a different color on each CD, I suspect that the bootable disk was created in isolation, and I simply stored both CD's in the same case.
When I performed the Repair on my daughter's machine by using the bootable XP install disk, I used the product key that was written on the authentic Windows CD. The system accepted it and I was able to validate that copy of Windows.
OK, so now let's move on to the status of my machine, the machine I was concerned about putting on the network because I didn't know if it had a matching Product Key.
Here's what I did:
I turned off Auto Updates, put it on the net, downloaded Magic Jelly Bean and ran it.
The CD Key does not match the key that I used on my daughter's machine. In other words, it does not match the Product Key written on the authentic Windows CD. That tells me I can have both machines on the net at the same time with no worries.
So here's the next question: As I mentioned in my OP, the use of the Repair utility significantly improved the performance of my daughter's machine. Let's say I wanted to try the same thing on my machine. If I use the same bootable XP install disk on my machine and use the CD Key found by Magic Jelly Bean on that specific machine, will it accept it?
In other words, is the bootable XP install disk just a "generic" install disk that can be used on any XP machine or did it work on my daughter's machine because the Product Key I entered (from the genuine Windows XP disk) matched what was on the bootable XP install disk? Is there even a Product Key on the bootable disk or does the utility just want make sure that you know what key is on the machine you are repairing?
Thanks again for your help.
