Have you ever wanted to display a certain dialog just by clicking on a shortcut? Maybe you wanted to have a shortcut to open the Mouse Control Panel, and display the Buttons page by default (so that you can easily reconfigure your mouse buttons to work for playing games or something). Well, using rundll32.exe, you can do just that, among many other things.

While I always knew that you could do a couple of things with rundll32, I never knew just how much until I stumpled across this page. There are a ton of different things that you can do, it’s really quite amazing.
