Windows 10: Motherboard and CPU upgrade after failure Win10 now says I do not have a valid license key...

Hello,


My motherboard went and I upgraded the CPU during it. I now have a watermark to "Activate Windows". When that is attempted, I receive error code 0x803F7001 and troubleshooting is unable to locate my device.


What can be done about this?

Licensing confusion after upgrading motherboard and CPU

I recently upgraded the motherboard and CPU in an OEM desktop. This OEM originally came with Windows 8.1, and was upgraded to Windows 10 upon its release last July.

I found out after my hardware purchase that, since I had an OEM copy of Windows, I would have to purchase a new license in order to reinstall Windows 10. On a whim, however, since I had previously obtained a copy of my OEM license key from the original motherboard's
BIOS, I tried entering it in to validate Windows. Surprisingly, it worked.

My question is, did I somehow have a retail copy of Windows all along, which would have allowed me to transfer the license to a different PC, or am I in violation of Microsoft's EULA. If so, what should I do?

 

Windows 10 Pro's license completely glitched out after changing motherboard and CPU

We appreciate your reply. For us to know more about the issue, kindly answer the following questions:

• Did you manage to deactivate Windows 10 Pro first before replacing your motherboard?
• Do you still have the written copy of your product key?
• Are you using the same hard disk where your Windows 10 Pro product key has been activated? If not, where is this hard disk?
• Did you replace your hard disk along with your motherboard and CPU?
• What is the edition of Windows activated on your computer? To know, press Windows + S. Type About, and click it.

Meanwhile, we recommend that you deactivate and uninstall your Windows 10 Pro license from your old motherboard and reinstall it back on your machine using the steps below:

Step 1: Check your your Windows 10 Pro product key using Windows Powershell or Command prompt. Follow the steps below and note down your product key:

• Press Windows key + X.
• Click Command Prompt (admin).
• Enter the following command: wmic path SoftwareLicensingService get OA3xOriginalProductKey
  and press Enter:
• The product key will be revealed, copy the product key.

Step 2: Deactivate and uninstall the Windows 10 Pro Product Key from the old motherboard since it has your license. Follow the steps below:

• To know the Activation ID of your Windows installation. Open a command prompt using the Windows search box and type in
  slmgr.vbs /dlv and press Enter. This will display the detailed license information for the installed operating system.
• A window will open up and will give you details about your Windows licensing and activation status. Look for
  Activation ID and note it down.
• On the same command prompt window, type in slmgr /upk <your Activation ID> and press
  Enter. This uninstalls the product key of the current Windows edition. After a restart, the system will be in an Unlicensed state unless a new product key is installed.

Step 3: Activate your Windows 10 Pro to your machine after uninstalling it due to a hardware change, follow the steps below:

• Open a command prompt using the Windows search box and type in
  slmgr /ipk <Windows Product Key> and press Enter.
• If the key is valid and applicable, the key is installed. If a key is already installed, it is silently replaced. If the key is invalid, an error is returned.
• Open your Control Panel you will see Windows is activated message.
