EmptyDesk

EmptyDesk will not clean your actual desk, nor will it organize a virtual one, or teach you about the benefits of cleaning your work area. This application will help you hide the contents of your desktop by placing a black cover or filter over it. It's a great short-term solution if you'd like to keep away curious people. You could employ its use while taking a short break, when a surprise visitor surfaces, or simply when you'll need to tidy your desktop real quick.

The application is made up of a small window containing two specific buttons. One is for hiding the stuff on your desktop, a.k.a. applying the dark cover, and one is for bringing everything back to normal. The application doesn't do much else. Still, as far as usefulness is concerned, this program manages to offer exactly what is advertised. It's useful for all sorts of scenarios. It won't bother you in any way. You can use it only when you require its services.

Looks might not be great, nor the palette of functions, yet somehow this app seems to be much more helpful than a lot of other apps out there, and this might be simply because unlike those, EmptyDesk has a simple and well-defined mission.
