Add "Command Prompt Here" Shortcut to Windows Explorer

Through the Registry

Navigate in your Registry to
HKEY_LOCAL_MACHINE/Software/Classes/Folder/Shell
and create a key called "Command Prompt" without the quotes.

Set the default string to whatever text you want to appear in the right-click menu.
Create a new key within your newly created command prompt named "command," and set the default string to
cmd.exe /k pushd %1
You may need to add %SystemRoot%\system32\ before the cmd.exe if the executable can't be found.

The changes should take place immediately. Right click a folder and your new menu item should appear.
