In tip 0484, we disabled the Windows keys.

Keyboard remapping is controlled by the optional Scancode Map Value Name, a REG_BINARY data type, at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout.

The general format of Scancode Map is:

Bytes     Data              Description                              0-7       0000000000000000  Header                              8         XX                A hexadecimal number defining the number of key remappings, plus 1.                              9-11      000000            Always zeros
Each subsequent entry is 4 bytes. The first 2 bytes are the remapped key code, or zeros to disable the key, and the next 2 bytes are the key code to remap.

The last 4 bytes are a trailer which is always zeros.

NOTE: If you are remapping keys, instead of disabling them, you might want to use the ReMapKey.exe freeware.

NOTE: Once you have defined Scancode Map, you must restart your computer to implement the defined remapping.

NOTE: To remove all remapping, delete the Scancode Map Value Name and restart your computer.

NOTE: Download the Keyboard Scan Code Specification.

If you wanted to disable:
