Use Your Screen Saver as a Security Device
With modern monitors, screen savers aren't really needed to prevent images from "burning in" to a CRT or flat-panel display. But a properly configured screen saver can be a valuable security aid, especially in homes and offices where physical security is lacking and you're often away from your desk. Open the Display option in Control Panel and click the Screen Saver tab. Select any screen saver, and then adjust the following two options, as shown in Figure 2-12:

Select the On Resume, Password Protect box (Windows XP) or the Password Protected box (Windows 2000).
In the Wait box, dial the default setting down to the minimum level you can tolerate. For maximum security, make this value no more than 5 minutes. This is the period that Windows will wait following any inactivity before the screen saver kicks in.

Figure 2-12. To make it more difficult for unauthorized users to access your computer when you step away from it, set screen saver options as shown here.
