Windows 10: Windows 10 deactivated following update, product key not working to reactivate it

Hi there,

I recently updated Windows on my Lenovo ideapad, and since then I have had numerous issues. The biggest one of which is that Windows has deactivated itself, and the original product key which I found by downloading a program to find as it is internally stored within the laptop does not work when input to reactivate windows. I have tried running command prompt and entering the wmic path softwarelicencingservice get OA3xOriginalProductKey code, but that just brings up an error message, ERROR: Description = Not found.The computer was bought with Windows already on it, so there's no way the activation code can suddenly be invalid as far as I know. I also had real problems with the network following the update, which after lots of effort were only fixed by resetting the laptop to factory settings. Any advice on how to fix this windows activation issue would be massively appreciated, I've seen a lot of posts on this issue on the forums here and followed all the advice, but nothing has worked. If anyone has any idea why this has happened that too would be handy to know.

:)

 

deactivate windows product key

How do I deactivate a Windows product key from another computer? All the answers I found refer to deactivating a product key on the same machine but I can't do that because the the machine was reinstalled with Linux without deactivating the product key.
My case is specifically for Windows 7 but for the sake of the question if there's a method that works for all versions of Windows that be preferred.

Thanks.

P.S. for the topic category I said activate since I'm looking to deactivate the license so I can reactivate it.

 

Windows 10 which came with free upgrade deactivated itself

Hello Turin,

Thank you for reaching out to us. The installed copy of Windows 10 is a volume license that requires a reactivation, this is the reason why your Windows 10 deactivated itself. You may still use your product key due to digital entitlement that will enable
to reactivate Windows 10. For us to help you with your concern, we suggest that you retrieve your product key using the Command Prompt:

• Open Command Prompt (Admin) by right clicking the Windows icon. On the Command Prompt window type in the following and press
  Enter: wmic path SoftwareLicensingService get OA3xOriginalProductKey.
  
• Copy the product key and go to Settings > Update and Security > Activation > Change product key. Paste the product key and proceed with the rest of the process.
  

Kindly get back to us.
