Chapter 1: Start Here First
Turn on Windows Update
Bored youngsters work late nights probing Windows to locate programming problems.
When they discover a new flaw, they write a virus or worm (a small, malicious
program meant to do damage, such as erasing important files) to take advantage
of it. These kids release the virus, and it begins damaging people’s computers as it
spreads worldwide.
When alerted to a new security exploit, as they’re called, Microsoft programmers
scratch their heads and wonder what’s wrong with today’s youth. Then they
release a special piece of software to fix the problem. To grab that special software,
called a patch or update, your computer needs Windows Update.
Microsoft’s free Windows Update program automatically downloads patches that
plug the latest holes found in Windows’ defenses. Windows Update works only if it’s
turned on, however. Follow these steps to make sure Windows Update is turned on
and working to protect your computer.
1. Click the Start button and choose Control Panel. Then choose System and
Security, as shown in Figure 1-1.
The System and Security window appears. If you see a sea of icons rather than
what’s shown in Figure 1-1, click the Windows Update icon, and click Change
Settings from the window’s left pane.
Still using Windows XP? Then click the Start button, click Control Panel, and
click Security Center.
