HKEY_LOCAL_MACHINE/System/CurrentControlSet/services/Kbdclass/
HKEY_LOCAL_MACHINE/System/CurrentControlSet/services/Mouclass/

are the keys for enabling and disabling the keyboard and mouse. set the
value to REG_DWORD 4 to disable keyboard/mouse support and REG_DWORD 1
to enable ..

after setting the values you have to reboot the machine in order to
achieve the desired behaviour.
see attached part of a perl script.
