Windows 10: Windows Activation Error after Hardware Upgrade

Hey,


I recently upgraded some hardware in my PC, and now it says that I need to activate windows.

I upgraded to Windows 10 from Windows 8.1 so I don't have a product key, and the troubleshooter gives me an "Unable to activate windows" error after I try to select which PC I am using.


How do I fix this?

Thanks!

:)

 

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

 

Windows 10 wont "Activate" after hardware upgrade

Hi, fcp4life,

Follow the steps listed in this Support Doc.

Reactivating Windows 10 after a hardware change

https://support.microsoft.com/en-us/help/20530/...

If you made a significant hardware change to your device (such as replacing the motherboard), Windows 10 might no longer be activated and you might see the activation error codes 0x803f7001 or 0xC004C008.

If your Original Hardware Manufacturer (OEM) changed the motherboard for you, your PC should reactivate automatically or you should be provided with a replacement product key. If you see the Activation error “Unable to reach Windows activation servers,” then
follow the steps in this additional help article.
