One common misconception is that if you are a Microsoft Volume License Customer, you can use your Volume License media to install the initial full Windows license on a new PC. It's important to understand that Volume License Agreements offer Windows Upgrades only and not full Windows licenses. Therefore the OEM Product Key affixed to a new PC "is not a spare" and cannot be reused with a different PC.
