New Version of Windows XP to Combat Lack of Product Keys

The current version of Windows XP Service Pack 2.0b is currently running very low on product keys, due to piracy the surprising longevity of the product. And so, to combat the lack of product keys, Microsoft is creating a fresh batch by releasing Windows XP Service Pack 2.0c. There should be no major differences, other than the latest patches built in and the new abundance of keys.

This version of XP will only be available to OEM system builders, and will only be in the market until Windows XP's official EoL date: January 31st 2009. Retail copies of Windows XP will stop shipping on the January 31st 2008.

Cannot upgrade to Windows 10 - Unique Product Key situation

No... let me try again.

• Old computer is running Win7 Pro (SP1) with a Product key I have from a few years ago. The Product is activated already, but I do NOT use this computer at this point, so I didn't worry about using the Product key when moving to the new computer (see below).
  
• New computer is running Win10 Pro, with data and OS migrated from the Old computer, (same Product key as above), then Upgraded to Win10 (without getting a new Product Key).

What I am trying to do now...

• I want to upgrade the OLD computer (Win7 Pro) to Windows 10... using a new Product Key I just purchased.
• I have tried to do this internally, and also using the ISO burned to a thumb drive. But it does not want to work.
• Steps:
  • Start from USB drive.
  • Enter New Product Key (or click "I don't have one").
  • Install initiates and then tells me to restart from Windows and then open the installer again to continue.
    • At this point, I actually need to Quit the installation to restart the machine.
  • When restarted, I go to the USB drive and restart/resume the installation process.
  • I have tried to download and not to download updates, but when the installation fails, I see the message, "Something happened" and "Setup has failed to validate the product key".
  • NOTE This happens if I enter the NEW Windows 10 Product Key, or if I skip that step (which I assume means that it will use the old Windows 7 Key for the upgrade).
