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.

Activate Windows 10 Aniversaire ver. 1607 build 14393.10 after changed motherboard.

My PC

-Motherboard ASUS P5QL PRO, chipset P43

-CPU Intel E8500 socket 775,

-OS Windows 10 Pro, after upgrade to Ver.1607 build 14393.10

-Windows is activated with a digital license linked my Microsoft account.

After that, I've changed motherboard with the new one Gigabyte H81M-DS2 chipset H81 (included CPU Intel i3 4350T socket 1150).

I signed in Windows by password of my Microsoft account as administrator and use the
Activation troubleshooter solution to reactivate Windows, in step select "I changed hardware on this device recently" then click "Next" but I don't see where the list of devices that are linked to my Microsoft
account, so that I can't reactivate Windows.

I return back to old motherboard ASUS and CPU E8500: Windows activated as it was.

Someone know about this problem please help me reactivate Windows 10 build 14393 after changed motherboard, or tell me know that it's unable!

Thanks and Regards
