If you buy a 10 Pro key yourself there are no downgrade rights to 7 Pro.

10 Pro has to come preinstalled by the OEM (Dell, HP, etc.) for Downgrade Rights.

Here is the information about Downgrade rights. It is an old Microsoft link which they removed but the information still apples>

Activate windows 10 after re-installing (I have lost my product key)

I own a Lenovo T430 laptop. In 2017, I installed Windows 10 using my original Windows 7 product key. Unfortunately, I cannot find that product key anymore. I need to re-install windows 10. Will it be automatically activated after the installation, if I skip the step of asking the product key during the installation?

In my opinion, I believe that my laptop will have a digital entitlement stored on the Microsoft Activation Servers and this will not be a problem. Is that true?

If not, please suggest me a solution or a workaround.

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.
