- Enter the key of previously used Windows version (e.g., Windows 7, Windows 8). However, if you do not have it, enter your current Windows 10 key.
- After saving the changes, reboot your computer.
However, some of the users claim that they receive an error when navigating to the Activation settings. The error claims that “Activation failed because this device doesn’t have a valid digital entitlement or product key.

- Go to Settings -> Update and Security -> Activation -> Change product key.
