The keyboard filter module allows you to block certain keys or key combinations, great for blocking access to the Windows 10 Virtual Desktop manager so users cannot create a new virtual desktop to hide in.
The keyboard keys map directly to the Windows Keys Enum, found on the Microsoft website here: https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.keys
Usage Rules:
- Enter a single Key to block that Key, such as LWin and the Left Windows Key will no longer function.
- Enter multiple Keys separated by + and the first keys will represent Modifier Keys, for example: LWin+R ... this will block the user opening the Run Box using the left Windows Key
- Enter multiple Blocks by separating the commands by semi-colon ( ; ) .. for example: LWin+R;RWin+R will block the Run Box from both the left and right windows keys
Here is an example that will completely block the a new Windows Virtual Desktop from being created, and also block the Windows+Tab Application/Desktop Manager from opening:
LWin+ControlKey+D;RWin+ControlKey+D;LWin+Tab;RWin+Tab
Each of the above 4 key combinations will be blocked.
It is recommended to test your Key combinations on a pc by running it directly, then once successful, copying the command to a new policy.
