Windows 10: Somewhat unique problem with activating new windows 11 product key

Hi, I'd like some help or at least some options of what I can do at this point. What I've done so far: I purchased components needed and built a new desktop computer. I was having issues with it black screening on boots and reboots. I purchased a new windows 11 home product key for $100 and tried installing Windows 11 via a usb stick. It wouldn't boot several times then finally it decided to; I tried the installation and I got to the point where it copied all the files onto the SSD and I entered my new product key and it accepted it. After the computer needed to restart it black screened

Windows won't activate a digital license but will with a product key?

If you plan on "transferring" a digital license from one computer to another using the activation troubleshooter and your Microsoft Account, then yes, start with the generic product key on the new computer. Actually, on a new install, you select the option for "I don't have a product key" and then after the install use the Activation Troubleshooter.

Otherwise, if you are using a unique product key, either purchased or embedded in the firmware of the computer by the factory - let Windows 10/11 activate for the first time from that product key. AFTER it is activated, change the product key to the generic. One advantage to doing this is that if the original product key was OEM, changing it to the generic retail product key will also change the digital license type to retail and make it transferrable to another computer.

 

Cannot upgrade to Windows 10 - Unique Product Key situation

No... let me try again.

• Old computer is running Win7 Pro (SP1) with a Product key I have from a few years ago. The Product is activated already, but I do NOT use this computer at this point, so I didn't worry about using the Product key when moving to the new computer (see below).
  
• New computer is running Win10 Pro, with data and OS migrated from the Old computer, (same Product key as above), then Upgraded to Win10 (without getting a new Product Key).

What I am trying to do now...

• I want to upgrade the OLD computer (Win7 Pro) to Windows 10... using a new Product Key I just purchased.
• I have tried to do this internally, and also using the ISO burned to a thumb drive. But it does not want to work.
• Steps:
  • Start from USB drive.
  • Enter New Product Key (or click "I don't have one").
  • Install initiates and then tells me to restart from Windows and then open the installer again to continue.
    • At this point, I actually need to Quit the installation to restart the machine.
  • When restarted, I go to the USB drive and restart/resume the installation process.
  • I have tried to download and not to download updates, but when the installation fails, I see the message, "Something happened" and "Setup has failed to validate the product key".
  • NOTE This happens if I enter the NEW Windows 10 Product Key, or if I skip that step (which I assume means that it will use the old Windows 7 Key for the upgrade).

 

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
