After receiving my computer (with XP Home) I formatted the disk and installed XP Pro which I already have a licence for, plus wanted a "clean" install.

I now need to find the product key for the 15 month McAfee security suite subscription I purchased with the computer.  I remember reading somewhere a web site link with instructions for doing this, but cannot find it now.

Can anyone help with the link or instructions?

Dell e-mail support are responding with a generic e-mail about how to uninstall the McAfee 90 day trial, which is not helping!!
