A bunch of tips and tricks for Windows. One of my favorite ones is where you can get a "Open Command Prompt here" menu option via Windows Explorer.
Q: how do you change the default location for the command prompt?
A: The best way I know of to do this is just to open the prompt from
within Windows Explorer. The following Reg changes will cause an open
command prompt here message to appear in the right-click menu.
@="C:\\WINNT\\System32\\cmd.exe /k cd \"%1\""
