I love taking photo's and have tons of them but I didn't get to look at them often enough until I created my own screen saver using some of my favorite photo's.  
Follow the few simple steps below to see more of your favourite memories.  

Rick-click on an empty area of the desktop and the click on "Properties" as shown below.

Click the Screensaver tab as you can see in the picture below, scroll down the list and click "My Picture Slideshow".

By default it will use photos stored in My Pictures but you can switch to any other folder by clicking the "Setting" button (circled in the screenshot above) and from there you can choose which folder you would like displayed.

"Play around" with the other options - you can't mess anything up.

Have fun!
