When I had received this computer, it was running an activated version of XP Pro. Since then, I have reinstalled this software and now I'm unable to locate the Product Key to activate it. This computer was originally running Windows Vista Business and was downgraded to Windows XP Pro (By DELL, I think)

How am I able to activate this copy of Windows XP Pro?

Quote

"That is the process. Install any copy of XP with any product key and then ring microsoft to activate - you will then need to quote a non activated vista key and they will profide a activation key for the XP install."

Is this true?

Welcome to Geeks to GO

If the computer has the COA (Certificate of Authenticity) label with the product key for Vista Business edition, then it appears that it falls within this parameter

the only people who can assist is Microsoft, your first line of enquiry and Dell, but of course they will be unlikely to help, depending on the age of the system.

The other question of course is, and no doubt it will be a subject that Microsoft will ask
"From which source have you reinstalled XP"?

So in summary contact Microsoft
