Windows 10: Unable To Activate After Hardware Upgrade

Hello,

I recently upgraded my motherboard and in the process must have forgot to link my microsoft account to my copy of windows 10 pro retail from a windows 7 pro upgrade. When I tried to use my old hardware, windows 10 still detected changes and I cannot reactivate.

I no longer can find the old windows 7 pro key, does this mean I'll have to repurchase windows?

Currently have recreated my computer pre-hardware upgrade on a makeshift test bench in case that will help.

:)

 

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.

Unable to activate Windows after hardware upgrade

After upgrading motherboard, video card and memory, Windows is now "deactivated".

Error code is: 0x803F7001





I tried using Troubleshoot. It says: We weren't able to activate Windows on this device.

I clicked the "I changed hardware on this device recently". I get a list of device which lists my device name.





I select it. Click Activate, and it says: Unable to activate Windows.

What else can i try/do?

 

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.
