Choosing and Conﬁguring Your Screensaver
Screensavers turn on when a computer has been idle for a specified period. Origi-
nally, screensavers were designed to prevent image burn-in on CRT monitors by dis-
playing a continually changing image. With today’s monitors, burn-in is not much of
a problem, but screensavers are still around because they offer a different benefit
today: the ability to password-lock your computer automatically when the screen-
saver turns on.
Windows Vista performs many housekeeping tasks in the background
when the computer is idle. These housekeeping tasks extend to creat-
ing indexes, defragmenting hard disks, creating whole computer back-
ups and system restore points, and more. Because of this, you want to
be more careful than ever when choosing a screensaver for your com-
puter. So, while you can install your fancy fish-tank screensaver with
the sharks and stingrays, you may do so at the expense of your com-
puter being able to perform background tasks while you are away
from your desk rather than while you are sitting at your desk.
