Windows Product Key

A friend of mine has an all-in-one that came with Windows 8 pre-installed. He erased the original OS thinking he could install another version of Windows 8. One thing he encountered, that he didn't expect, the BIOS/UEFI has a password. So, basically he is locked out from installing another OS. His BIOS has the product key nestled inside. Is it possible to find out which version the product key belong to?

 

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.
