Alt+F7 stopped working

Open NVidia GeForce Experience Settings -> General

Disable Share totally (newer: In-Game Overlay). This will free the binding of Alt F7 among lots of others.

If you do use Share feature you can use this alternative:

Press Alt + Z when you are on desktop for example: Settings -> Keyboard Shortcuts Change the binding of Alt + F7 to something else.

Could not add comments and upvote answer with Nvidia Geforce Experience as an issue. It helps me too, but I does not reinstall, I just disabled Alt+z hokey in settings - "share" functionality.

Yes, NVidia GeForce Experience was the reason! However, on my PC it was not called "Share", but "IN_GAME OVERLAY". As soon as I disabled the IN_GAME OVERLAY, all shortcuts in Far started working.
