Reinstall Windows 10 with OEM product key

When you upgraded from a previous version of Windows or receive a new computer preinstalled with Windows 10, what happened is the hardware (your PC) will get a digital entitlement, where a unique signature of the computer will be stored on Microsoft
Activation Servers. The Windows 7 or Windows 8 genuine license you were previously running will be exchanged for a diagnostics key.

Anytime you need to reinstall Windows 10 on that machine, just proceed to reinstall Windows 10. It will automatically reactivate.
You will prompted to enter a product key a couple times through the installation, click I don't have a key and Do this later.

There is no need to know or get a new key, but if you have issues with Digital Licensing or the Activation Troubleshooter, you can utilize an existing Windows 7 or Windows 8/8.1 product key
you already ownto reactivate if necessary. or use the reset function in Windows 10.

OEM Product Key - Tool Available To Reveal It

Newer PCs and laptops shipping with Windows 7, Windows 8, and Windows 10 no longer come with a Certificate of Authenticity attached to the back or bottom of the PC. Instead, PC manufacturers have worked with Microsoft to embed the product key directly into the BIOS or EFI.
If you need to retrieve the OEM-embedded product key from your PC, you can use this OEM product key utility to extract and show the product key programmed into your PC. Absolutely no user interaction is required, you just run the download and it immediately displays the detected product key. This product key can be used to reinstall Windows 10 and Windows 8 with a clean Windows setup CD to remove bloatware installed by the manufacturer, or to reinstall Windows after a crash or system failure.
