With this tip, you can right-click any folder in your windows and open a command prompt at that folder. It is a very old hack and I am mentioning it here because of compulsion.
Run the Registry Editor and navigate to
HKEY_LOCAL_MACHINE/Software/Classes/Folder/Shell. Create a new key called Command Prompt. For the default value, enter whatever text you want to appear when you right-click a folder.. Create a new key beneath the Command Prompt key called Command. Set the default value to Cmd.exe /k pushd %
L. That value will launch Cmd.exe, which is the XP command prompt. The “/k” switch puts the prompt into
That is, it lets you issue commands from the command prompt; the command prompt isn't being used to issue only a single command and then exit. The “pushd” command stores the name of the current directory, and “%L” uses that name to start the command prompt at it. Exit the Registry.
