Swapping CapsLock and Control on NT 4.0

----------------------------------------------------------------------------
* In NT 4.0, installation of keyboard layouts have changed. The file
layout.inf is no longer used for keyboard layouts. Instead, different
layouts are setup in the registry. The regsetup.exe program will set these
values for you.

* For changing CapsLock to Control, copy kbdussw.dll to your
%SystemRoot%\System32 directory, where %SystemRoot% is normally something
like c:\winnt or c:\winnt4.

* For swapping CapsLock and Left Control copy kbdussw1.dll to your
%SystemRoot%\System32 directory, where %SystemRoot% is normally something
like c:\winnt or c:\winnt4.

* To use the U.S. Dvorak layout and change CapsLock to Control, copy
kbdusdvsw.dll to your %SystemRoot%\System32 directory, where %SystemRoot% is
normally something like c:\winnt or c:\winnt4.

* Run regsetup.exe to set the values in the registry.

     For the US CapsLock is Control layout, run
          regsetup.exe

     For the US Swapped CapsLock and Control layout, run
          regsetup.exe swapped

     For the US Dvorak CapsLock is Control layout, run
          regsetup.exe dvorak

The registry values that it sets are:

HKEY_CURRENT_USER\Keyboard Layout\Preload
     2: REG_SZ: 00000409
     1: REG_SZ: 00060409 (or 00070409 or 00080409)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard
Layouts\00060409
     Layout File: REG_SZ: KBDUSSW.DLL
     Layout Text: REG_SZ: US-CapsLock is Control

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard
Layouts\00070409
     Layout File: REG_SZ: KBDUSSW1.DLL
     Layout Text: REG_SZ: US-Swapped Left Control and CapsLock

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard
Layouts\00080409
     Layout File: REG_SZ: KBDUSDVSW.DLL
     Layout Text: REG_SZ: US-Dvorak and CapsLock is Control

* Now logout and log back in, and the new keyboard layout should be working.
If you do anything with the keyboard settings via the control panel, you may
need to rerun regsetup.exe or reset the values under HKEY_CURRENT_USER and
logout and login again. If you stick with a single layout, this should work
fine.
