Free Screensaver Manager
This free desktop utility allows you to manage multiple screensavers on your computer. It has two main goals. Start installed screensavers randomly from a custom selection. Prevent temporarily a screensaver from starting when you need to maximize your processor or memory resources. For example, defragmenting your hard disk. It allows you to select which screensavers you want to enable or disable. Whatever the number of screensavers installed on your computer, you can select only the ones you want to see.
