Windows 10: Can't activate Windows 10 Pro after Motherboard replacement

I got my computer professionally built just over a month ago but had to get them to replace a faulty motherboard. Unfortunately its now not allowing me activate Windows. I definitely activated it before the motherboard broke and its definitely attached to my account (I can actually see 2 versions of the same computer in my Microsoft Account devices list). I've only ever used the Product Key on this computer too.

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.

Activating Win 10 after replacing Motherboard

I recently had to replace a motherboard on a Lenovo ThinkCentre due to a blown power supply. After recovering, Windows was not activated and I can't use the troubleshooter to remediate. This system was shipped with Win 7 Pro and upgraded to Win 10 during
the free promotion offer.

Does anyone have suggestions on how to get Win 10 reactivated in this scenario?

Also any thoughts on why Win 10 doesn't recognize the DVD or USB ports in File Explorer?

 

Can't reactivate Windows 10 Pro after replacing motherboard

Hi,

I've just replaced a faulty motherboard in my PC and tried to reactivate Windows 10 Pro via the Windows Activation troubleshooter. The license linked to my account is an upgrade from a retail version of a previous version (so i should be able to reactivate
it). After selecting the correct device to activate I am presented with the following error message:

Unable to activate Windows

We can’t reactivate Windows on this device. Try again later.

You can also activate this device by going to the Store and purchasing a genuine copy of Windows.

The "Learn more" page referred to does not help as I have just followed the steps listed on that page to get to where I am now.
