Convert a Windows 8pro product key to a Windows 10pro produkt key

Hi Andre,

Thank you for contacting Microsoft community.

I suggest you to Uninstall the license using the following steps.

• Press Windows key + X
• Click Command Prompt (Admin)
• At the command prompt, type: slmgr.vbs -upk
• Press Enter, this will uninstall the product key from the computer.

Further on, install Windows 8.1 activate the copy with the product key on the new machine. Then again upgrade the same to Windows 10 using Window Update or Media Creation Tool.

Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.

 

License Transfer question


So I found this on the MS website.

Add Windows 8.1 Pro Pack or Windows 8.1 Media Center Pack to your edition of Windows 8.1

• Swipe in from the right edge of the screen, and then tap Search.
  (If you're using a mouse, point to the upper-right corner of the screen, and then click Search.)
  
• Enter add features in the search box, and then tap or click Settings.
  
• Tap or click Add features to Windows 8.1 and then do one of the following:
  
  • If you need to purchase a product key, tap or click I want to buy a product key online.
    Follow the steps to purchase and enter a product key.
    
  • If you already have a product key, tap or click I already have a product key.
• Enter your product key and click Next.
  
• Read the license terms, select the check box to accept the license terms, and then click Add features.
  
  
  Would this be the way to do it? And would it matter that this would be the US version and not UK?
  
  Thanks
  Conor
