Opening a DOS Window to either the Drive or Directory in Explorer

Add the following Registry Keys for a Directory:
HKEY_CLASSES_ROOT\Directory\shell\opennew
@="Dos Prompt in that Directory"

HKEY_CLASSES_ROOT\Directory\shell\opennew\command
@="command.com /k cd %1"

Add or Edit the following Registry Keys for a Drive:
HKEY_CLASSES_ROOT\Drive\shell\opennew
@="Dos Prompt in that Drive"

HKEY_CLASSES_ROOT\Drive\shell\opennew\command
@="command.com /k cd %1"

These will allow you to right click on either the drive or the directory and the option of starting the dos prompt will pop up
