Windows 10: Can't figure out Windows Activation Key situation

I tried to troubleshoot it, but it didn't work despite having Wi-Fi. I tried updating to see if that helped, but nothing. Cleared out storage space, restarted the computer a couple of times, but nothing.I initially assumed that it was because I got this laptop from my school, which has been wiped and taken off the school's servers before I got ownership over it. Yet, I no longer think that is the case, as this hasn't been an issue until this week. However, I wanted to ask here before I try to contact support.

Windows 10 will not activate Error code 0x803F7001

thanks
I activated my Windows 10 from product key Windows 7

 

activate windows 7 oem key

There is no difference between the OEM disc and the Retail disc with Windows 7. A retail disc will accept a OEM or Retail key, and vise versa.

If the OEM Key wasn't going to work with the disc you have, it would have stopped you during the install when it first asked you for the key, not during activation.

What is likely the problem is that, since the OEM version has already been activated once, it is failing activation again. Activate it over the phone using the option given to you on the failed activation screen, and you shouldn't have a problem activating it.

Hi Christian,

Thank you for posting your query on Microsoft Community.

Please be informed that Windows 10 is free for the customers who has activated Windows 7 with Service pack installed on it and for activated Windows 8.1 customers.

For Windows Store issue, I would suggest you to try running Windows store app troubleshooter and check if it helps.

Follow the below steps:

  Type troubleshooting in the
  Search area on the taskbar.
  
• 
  Click on View all on the left panel of the Troubleshooting Windows.

  Select Windows store Apps.

  Follow the on screen instruction.
  

If the issue persists, let’s perform Windows Store reset.
