Windows Me had a similiar screen saver option, but Windows XP made the feature even better. Since many computer users take lots of digital pictures, why not put those pictures on display as your screen saver. Here's how in Windows XP (Windows 98 users see end of this tip):

1. RIGHT Click one time on a blank part of your desktop
2. Click Properties
3. Click the Screen Saver tab
4. Click the drop-down arrow next to the name of the screen saver and choose the "My Pictures Slideshow"
5. Click the Settings button
6. Make any settings changes you want. (I like displaying each picture for only 6 seconds and I also choose the 100% of screen size option.
7. By default, Windows will use the pictures you have stored in the "My Pictures" folder. You can click the "Browse" button in the settings area to choose any folder you like.
8. Click OK
9. Before clicking OK on the main Screen Saver screen, click the button that says "Power"
10. I set my Power Scheme to "Always On" and have the Turn off Monitor, Turn off Hard drives, and Standby all set to Never so that I can always enjoy my screen saver.
11. Click OK
12. Click OK again

That's it. Follow these steps again to change picture folders or make other settings changes.

Tip within a tip: When the screen saver is running, you can use the Left and Right arrow keys on your keyboard to move through your pictures!
