Disable Snipping Tool

I intended to disable the built-in Win + Shift + S shortcut, which launches the “Snip & Sketch” tool. Although I uninstalled “Snipping Tool”, the “Snip & Sketch” application could not be found or uninstalled, and whatever I tried, it remained active on the shortcut. For example, the command

Get-AppxPackage Microsoft.ScreenSketch -AllUsers | Remove-AppxPackagess

finds it and attempts to remove it, but unsuccessfully. In the end, I settled for simply disabling the shortcut key.

Disabling Win-key Shortcut

In Registry Editor, navigate to

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

add the key DisabledHotkeys as a String Value and enter the letter S or any other.

To disable Win + X, set the value to X. To disable both Win + X and Win + R, set it to RX. And so on.

To see the changes, you must restart Explorer or sign out and sign back in to your user account.

Finally I can redefine the shortcut and assign it to ShareX if I desire.

Simple Explorer Restart

To restart Explorer, we will exit and start again. First, launch a PowerShell terminal and then exit Explorer. Exiting Explorer is easiest by holding Ctrl + Shift while right-clicking on the Taskbar and selecting Exit Explorer from the menu. After that, type explorer.exe in the open terminal.
