Answer 2

Anytime you need to reinstall Windows 10 on that machine, just proceed to reinstall Windows 10. It will automatically reactivate. You will prompted to enter a product key a couple times through the installation, click I don't have a key and Do this later.

Activate Windows

Answer 3

There are end users that had downgraded Windows 11 to Windows 10 after the 10 day default rollback period.

A clean install was not required.

Answer 4

You can use same Windows 10 product key that you earlier used to activate it. If it is an OEM license, it may be automatically activated after clean install.

Answer 5

Hi there,

If it is an OEM key and digitally linked then you can just clean install and then it will be reactivated without any action from you. If it is retail and you have the key, just select the change product key and input your Key.

Here is a link for a detailed description of the process that you must follow.
