Windows 10: windows activation problem on mb changed

I've recently changed my motherboard and i can't activate windows 10 anymore, the error is 0x803fa067. What should i do?

:)

 

How to change the MB without having to reinstall windows ???

Suggestion

Before you turn off Windows for the last time prior to changing MBs, go to Device Manager and delete everything you can, with no mercy, especially the items under "System devices".
Then next time you boot (after changing MBs hopefully), Windows will re-install everything again, but this time according to the new hardware.
Works quite well... Good luck!

 

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

 

Activation problems after hardware changes and reinstallations.

Hi Meli,

Thank you for posting the query on Microsoft Community.

I do appreciate your efforts and time.

Was Windows 10 activated before re-installing it?

Along with the suggestions provided by Greg, you can also refer the steps below.



The only hardware changes that can negatively impact activation status once you upgrade to free version are the changes to the:

• CPU
• TPM
• Motherboard replacement

The following changes are examples of hardware changes that will NOT impact the activation status:

• HDD/SSD
• Video card
• Adding extra memory

If you replace the CPU, TPM, or Motherboard you may have to re-activate but this will not require a purchase of Windows 10.
