  1. Windows activation error after reinstall


    In my laptop, windows 10 professional was activated. I reinstalled windows 10 pro in it and tried to activate with my product key and I could not install with the error code 0x8007007B.

    How can I activate my window again?

    :)

    Windows 10 will not activate Error code 0x803F7001


    Possibly there can be the problem with Microsoft activation Server, so your Windows 10 is not activated. In this scenario, you need to wait and verify if it is the issue from Microsoft’s side. But if you are getting error code 0x803f7001, you can also try these steps:

    1. Open Settings app. Then go to Update and security > Activation screen > Change product.
    2. Type your Windows edition product key and click Next.
    3. You’ll get We couldn’t activate Windows error message.
    4. Retry steps 1-3 then type your 25-characters unique product key.
    5. Wait for the process to complete, Windows 10 is activated.
    Hope something helps this problem
