Part 4: Automatic Updates

Security updates and service packs correct programming errors, add new features, and protect against newly detected security vulnerabilities that could harm a computer.

When you use Windows Update, the update software examines which updates are required and makes them available for installation. You can specify one of the following methods of installation:

•	Automatic
•	Semi-automatic
•	Manual

Automatic (recommended)

Automatic is the recommended default setting. (You can specify this setting when you install Windows XP SP2.) If this method is selected, Windows automatically searches for updates when you connect to the Internet. If a new update is available, Windows downloads and installs it at the specified time or at the next system startup. The Windows Update icon appears in the taskbar when Windows is performing this function.

Note

You can visit Windows Update and manually install the updates, but this step is not required. You only have to take action if a restart is required. If this is the case, click Restart Now, or restart the computer later.

Update options in the Security Center

Your security status is only considered acceptable by the Security Center if you select the Automatic (recommended) option. Both semi-automatic options (2 and 3) are considered less appropriate. If either of these is selected, you are prompted to start the automatic updating option. If Automatic Updates is deactivated, this situation will be classed as a security risk.
