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

Hello Karthicka_R

thank you for your reply.

But as i wrote in my question: without any new installation.

• I have a valid installation of Windows 10home
• I can upgrade this to Windows 10pro but i have to pay it, i don't want to pay anything, because
• I have a valid Windows 8pro license key which i can upgrade to Windows 8.1pro and then to Windows 10pro, but i don't want install all new on my PC which is running Windows 10home.
  
• I want to get a Windows 10pro product key for my Windows 8pro product key and enter them in my Windows 10home in the 'Change Product Key Dialog' to bring my Windows 10home to Windows 10pro without any new installation.
• I can't believe that i can only upgrade my for an update to Windows 10pro valid product key only with a new installation.

Thanks for any answers.

Kind regards

Andre

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.
