Updating Windows 10 installation
Updating Windows 10 installation
You can use the "Reset this PC" option in settings without needing a Windows 10 key. The issue you're facing is likely because you previously upgraded from Windows 7 to Windows 10 using the free upgrade method, which may have left your system in a state that requires a new activation key. You don’t need to purchase a new key if you’re using the same Windows 10 version; just follow the reset process and it should restore your original setup.
When the Reset option encounters an issue due to missing components, you must use a Windows 10 installation media such as an install disk or USB drive to resolve the problem.
