This is a realy useful one.It alows you to rightclick a folder and open
a command prompt with the path of the folder already displayed :

- HKEY_CLASSES_ROOT\Directory\shell

Create a new subkey(right click on shell folder) and name it for example
commandprompt.Set the value in the right pane to that name you want
to have displayed on a right click.

Now create in the new created "commandprompt" key a subkey named :

command

and set the default value in the right pane to :

C:\Windows\System32\cmd.exe /k cd "%1"


Note :

You have added on a right click the option : (as you named it)
Click it and cmd prompt will open with the specified path displayed
