If you need to reinstall Windows 10 at any point you may be a little confused by the activation and licensing approach for Windows 10. It is not being displayed in the product key code box in system tools and if you upgraded from Windows 7 or Windows 8.1 you could use this previous key to get to activation for the current version, assuming you still have the old licence key.

Another method is to download the industry standard analysis tool Belarc and take a snapshot of all your system data such as programs installed and their respective licences, plus details about your computer specs, motherboard, hard drive and ram memory installed.

If it’s good enough for NASA it’s perfect for the rest of us.
