Windows 10: My product key not working after reinstall

My laptop was originally windows 7 with a windows 7 product key. I upgraded it to windows 10 three years ago and never had a problem. Recently my windows crashed and nothing worked, so I had to reinstall the windows from a media creation file. Now windows 10 is successfully installed but won't accept my product key anymore.

Product Key for reinstalling windows

Hi NAUFAL

I am an independent advisor here to help

in this situation but you will have is a digital product key or product license attached to the motherboard of the computer. There is no traditional product key to be had in the situation. When reinstalling Windows 10 you will see on the screen that asks you
to enter the activation key that you have the option to skip that step. Go ahead and skip that step, after set up as long as there is an active internet connection the Windows activation servers will read the digital activation license from the motherboard
of the computer and activate for you.

The only situation where this would not apply is if you have changed or upgraded the motherboard in your computer

 

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.
