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.

Windows 10 Activation after hardware change

• "You upgraded to Windows 10 using the free upgrade offer, but Windows 10 isn't activated after a reinstall. Your copy of Windows 10 should automatically be activated so long as you didn't make any significant hardware changes to your device (such as replacing
  the hard drive or motherboard)."

I just recently upgraded my motherboard, graphics card, and processor. Now my Windows 10 isnt activated anymore, and when i go through the steps to troubleshoot, it says the windows activation just says.

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.
