Configure the keyboard mapping using scancode map

It is possible to change the behavior of the different keys on the keyboard by changing the scancode map. This can be used to disable the Windows-key so one is not thrown out of your favorite game, when by accident have pressed the wrong key.

The change the scancode map, so the Windows-key is disabled add/update this binary value:


[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,03,00,00,00,00,00,5b,e0,00,00,5c,e0,\

For those who wants to know the meaning of the above values here goes:

00,00,00,00Header: Version. Set to all zeroes.
00,00,00,00Header: Flags. Set to all zeroes.
03,00,00,003 entries in the map (including null entry).
00,00,5b,e0Left Windows Key (0xe05b) -> Disable (0x00).
00,00,5c,e0Right Windows Key (0xe05c) -> Disable (0x00).
00,00,00,00Null entry.

To also disable the Shutdown key, one would extend the Scancode Map, so it has 4 entries where the fourth entry becomes ACPI Power Key (0xe0f6) -> Disable (0x00):


[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,04,00,00,00,00,00,5b,e0,00,00,5c,e0,\

Note it is also possible to map the the Shutdown keyboard key to become Sleep shortcut by going to Control Panel -> Power Options -> Advanced Tab.

    I opened regedit and saw I don't have HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout in my Windows XP Pro. What do I do? I don't want to disable the Windows key, just replace "/" to "?".

    And what about "$" ? shift+4.....I need this for a software I use in my office. I´d like to change shift+4 to other key without must to use shift. Thanks

    Didn't help. We use the pop-up keyboard and when we disable the Windows key, if you press the Close button right after pressing the Windows Key, the Start Menu pops up, or if you hit the Windows key twice, it behaves as if it wasn't disabled.

    Hello could you please let me know how to correct a registry for the letter "u" which on my keyboard, when typed brings an "a" letter. I suspect someone or a virus remapped my "u" letter to an "a".

    Thanks a lot for your help

      The registry-key "Scancode Map" does not exist by default, so just check if it exists for HKLM or HKCU. If it does, then just delete the key and restart.

  8. Timur says:

    Hi snakefoot , thanks for your answer. "Scancode Map" existed as I tried to correct the issue via a keymap SW, (remapping "u" to "u") I deleted it anyway as it didnt help bring back my "u", still typing "a". Also uninstalled / reinstalled keyboard drivers. That didnt help too... any ideas what could have caused this remap? Thanks!

    Thanks for the info. Very tough to find this stuff online. Question for you, if you are still paying attention to these comments... how do you get the scancode Map to implement without rebooting the system? I have a kiosk that I am trying to disable the ctrl-alt-del after 5 minutes... to give someone a chance to get in if needed. I can disable all these buttons, but the reboot is not desirable.

    Thanks for posting this though... really helpful.

    Great, but what of I need to usw a key with a longer code, like AltGr+0, which is E0 1F 0B ???
    How van I deal with that?

    Is there any way to disable the Print Screen button from keyboard (without breaking it the key of-course). I am using the windows 7.
