The major enhancements in Windows XP Service Pack 2 include Security Center, Automatic Updates, Windows Firewall, and Internet Explorer. This section describes these enhancements in detail.
Security Center: Security Center is an entirely new feature provided by Windows XP Service Pack 2. The Security Center service runs as a background process in Windows XP and routinely checks the status of the following components:
Windows Firewall Security Center detects whether Windows Firewall is enabled or disabled. Security Center can also detect the presence of some third-party software firewall products.
Automatic Updates Security Center detects the current Automatic Updates setting in Windows XP. If Automatic Updates is turned off or not set to the recommended settings, the Security Center provides appropriate recommendations.
Virus Protection Security Center detects the presence of antivirus software from many third-party organizations. If the information is available, the Security Center service also determines whether the software is up-to-date and whether real-time scanning is turned on.
