Windows 10: Unable to Activate Windows 10 after Factory Reset

Hello. I have recently factory reset my laptop due to some problems. However, after I reset the computer, it is asking me to Activate Windows, Windows was activated before I reset it. I tried to run the Troubleshooter but it says 'We weren't able to activate Windows on this device" Also, my error code is 0xC004F012.

See the windows is activated. And this is the screen which asks the product key. I can only skip this step if I boot from the dvd and select the clean install option.

"slmg /ato" returns Activating Windows core single language edition (a string of numbers and alphabets)
Product activated successfully.

You have to make sure the Win 8.1 reinstall is reactivated, not just assume because it's a factory reset. See tutorial here: http://www.eightforums.com/tutorials...-8-online.html and use the options and activation means appropriate to your particular version and license. There are command line methods (which NavyLCDR is well versed in) that you can also use to get an exact picture of activation, license type, and exact Win8.1 version that will confirm activation before you proceed to the WIn10 upgrade (and that is confirmed to match your exact Win 8.1 version).
