Microsoft Baseline Security Analyzer is a free tool that allows you to comprehensively check the security status not only of Windows, but also of Microsoft's most popular applications installed on your computer. MBSA detects unsettled vulnerabilities in Internet Explorer and Office. Check by connecting to Microsoft Update and downloading a list of available fixes, and then verifying which are installed and which are still missing in the system.

In addition, MBSA also checks a number of system settings for compliance with best security practices, such as the complexity of passwords and the status of automatic updates. After the scan is finished, the user is presented with a complete report with links to missing patches - so you can immediately find gaps. A great advantage of the program, especially for IT specialists and network administrators, is the ability to scan multiple computers wholesale via the network.

MBSA also offers the option to run from the command line. The user starting the program should be logged into the system with administrative privileges.
