Make a folder available as a toolbar on your desktop
I've been using Windows from many many years and I came across a feature that I had never heard of (this was explained in a family magazine as a hint for using Windows! :-S)
Try it for yourself: Take any folder on your machine, drag it and drop it on any side of your desktop (when half of the icon is visible). As you drop it, it immediately converts into a toolbar (there's no visual hint to tell you that this will happen). Once like that, you can do a simple click on any item to activate it exactly as if it were a button!
I'm happy because I've learnt something today! :-D
