You can start a cmd.exe command prompt in any subdirectory by right clicking it and slecting “cmd.exe” by adding the following to your registry:
Create the key “HKEY_CLASSES_ROOT\Folder\shell\cmd.exe\command“ and set the default value to a REG_EXPAND_SZ with this value:
“%SystemRoot%\system32\cmd.exe” /K PUSHD “%1″ & TITLE CMD.EXE %1
Here’s an example .reg file to do this, which can be downloaded here:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\Folder\shell\cmd.exe]
[HKEY_CLASSES_ROOT\Folder\shell\cmd.exe\command]
@=hex(2):22,00,25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,\
74,00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,63,\
00,6d,00,64,00,2e,00,65,00,78,00,65,00,22,00,20,00,2f,00,4b,00,20,00,50,00,\
55,00,53,00,48,00,44,00,20,00,22,00,25,00,31,00,22,00,20,00,26,00,20,00,54,\
00,49,00,54,00,4c,00,45,00,20,00,43,00,4d,00,44,00,2e,00,45,00,58,00,45,00,\
20,00,25,00,31,00,00,00
Also, in Windows Vista and newer versions, if you hold down the left shift key while right clicking on a folder, you get an extra menu item “Open Command Window Here” even without applying this registry change.
