Turn Toggle Key Sounds on or off in Windows 10 can enable or disable a tone that plays if you accidentally hit the Caps Lock, Num Lock, or Scroll Lock.

Two registry files are included:

Turn Toggle Key Sounds ON.reg
Turn Toggle Key Sounds OFF.reg

Double-click and click on Run, Yes, for the UAC prompt, and Yes, one more time to confirm Registry changes.

You can also make the changes in the Windows 10 Settings.

Advanced users can modify HKEY_CURRENT_USER\Control Panel\Accessibility\ToggleKeys

Double-click on Flags and use one of the following two numbers:

58 - Off
59 - On

This tweak is included as part of MajorGeeks Registry Tweaks.
