On 9 August 2005 Microsoft is planning to release 6 Security Bulletins affecting Windows. The highest Maximum Severity rating for these is Critical. These updates will require a restart, and will be detectable using the Microsoft Baseline Security Analyzer (MBSA).
The Microsoft Baseline Security (MBSA) is an easy-to-use tool that helps small and medium businesses determine their security state in accordance with Microsoft security recommendations and offers specific guidance for remediation. You can improve your security management process by using MBSA to detect common security misconfigurations and missing security updates on your computer systems.
