Manual crash dumps on Windows

Microsoft KB http://support.microsoft.com/kb/244139 about generating a memory dump file by using the keyboard was not clear for me in terms of how to generate crash dump using custom key sequence instead of ctrl-scrollock. 

After some googling, I have created these reg-files to generate manual crash dump on Windows by pressing "Ctrl-D" twice:

For PS/2 (notebook keyboards works too):
REGEDIT4
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\i8042prt\crashdump]
"Dump1Keys"=dword:00000020
"Dump2Key"=dword:00000021
For USB keyboards:
REGEDIT4
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\kbdhid\crashdump]
"Dump1Keys"=dword:00000020
"Dump2Key"=dword:00000021
Just copy-paste one from above to file with crash.reg, run it, restart the system and you will be able to generate crash dump manually with custom key sequence by pressing Ctrl-D twice.
