It depends on how long ago upgraded. After 30 days, traces of the old system normally vanish.

I need to go back to the laptop and look it up. It is a Dell. That much I know and I am going to try to do what Ramin suggested as well. I may end up just getting the upgrade license and make my life easier. I am betting it was a home version. Next to find out how much or the cheapest way to get the upgrade license. The gentleman is a priest so I am trying to help. The last tech charged him for messing it up. I am trying to clean up his mess.

If Windows.old is still there then you have also another option.

Download NirSoft’s ProduKey, run it on that computer and point ProduKey software at Windows.old .

Find the Download link at the Bottom of the page.
