My freeware, Ribbon Disabler, allows you to enable and disable the Ribbon UI in File Explorer in Windows 10, Windows 8.1 and Windows 8with just one click. Let's see what's new in this release.
In version 3.0, I made the following change.
if you upgraded a previous Windows version, the application now is able to detect it. It will not allow you to restore the Ribbon using older system files. Instead, you must disable the Ribbon again and will be prompted to do so.
If you have upgraded your OS from an earlier Windows release, please download Ribbon Disabler 3.0 first and then use it to disable the Ribbon. Don't use previous releases of Ribbon Disabler, or you will end with a black screen.
