Windows 10: Microsoft 10 Activation

I just purchased an Onn Laptop from Walmart. Windows 10 is already installed but I keep getting prompted to activate it. When I try to activate, I am getting an error code 0xC004F200. It is saying that my product key was already used on another device. Can you please tell me how to fix this?

Step 1: Check the Status of the Windows Activation

1. Open the Run command (Windows Key + R Key)
   
2. Type in ‘Control system’ and hit ‘Enter’.
   
3. Check the status.
   
4. Let us if you see ‘Windows is activated’ on System Properties Window.
   
   
   

If the Windows is not activated, try to activate with the product key.

Windows product key is a 25-character code used to activate Windows



Step 2: Activate with the Windows 10 product key

1. Open the run command (Windows key + R Key)
   
2. Type in “Slui 3” and click on ‘Activate’ and then check the status of issue.

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
