If you don't know of such a solution, then simply leave the question unanswered. The answer I am looking for is a solution that is specifically known to work with a refurbisher's product key. This is a possible solution, but one which I have not had time to try yet. Is there any way to get back to Windows 10 Pro using the product key on the sticker? I already tried following Microsoft's directions by entering that key in the Activation page of Settings, but Windows says it is invalid.Īnswers to a different question state that with a retail Windows 10 Pro key, one can modify the installer ISO to use that key automatically, and it will take precedence over the key in the BIOS. However, the new install of Windows 10 automatically activated itself with a Windows 10 Home key that is apparently embedded in the laptop's BIOS. I then installed an SSD into the laptop and did a clean install of Windows 10 using an ISO image downloaded from Microsoft.

I recently purchased a refurbished HP laptop that came with Windows 10 Pro installed and has a "WINDOWS 10 PRO FOR REFURB PCS" product key sticker.
