ME & XP Screen Saver Fun
So, while we’re in the Display Properties window, let’s mess around with your boring screen saver!
Just select the Screen Saver tab from the Display Properties window (you can obtain this by right-clicking on your desktop and selecting Properties ).
From there, you can select a screen saver and configure it exactly how you want it.

One of my favorites is the “My Pictures Slideshow.” Once selected, you should click the Settings button to configure it.

You can adjust where it obtains the photos (default is your My Documents/My Pictures folder), how often it changes the pictures, and how big the pictures should be.
