Vista product key is not validating
Any CD will do, but it's your possession of a unique product key that verifies you as having purchased a legitimate copy of the product. Microsoft is fairly vague on the details of "product activation", but it's likely that one of the things it checks is that the product key you entered is unique, and not already in use by someone else, or on another machine.
Whether you want to install Windows 10 in Boot Camp, put it on an old computer that isn’t eligible for a free upgrade, or create one or more virtual machines, you don’t actually need to pay a cent. You can download it directly from Microsoft, and you don’t even need a product key to download a copy.
If you visit that page on a Windows machine, it’ll redirect you to the download tool page instead.
Just begin the installation process and install Windows 10 like you normally would.
It's an excellent alternative solution to changing the Windows XP product key code manually. Try my Step by Step Guide to Changing the Windows XP Product Key for an easy walkthrough!

But beginning with Windows XP, PC makers were able to dramatically change the Windows install disc, so much so that, in some cases, those discs weren't even identifiable as valid install media to Windows Setup. In Windows Vista, Microsoft supported in-place upgrades from Windows XP, but if you wanted to use an Upgrade version of the Windows Vista Setup disc to do a clean install, you had to perform a weird double install trick.
