I originally wanted to take a look at MBSA (Microsoft Baseline Security Analyzer), but found that Microsoft has stopped updating it for a long time. I remember that when I wrote "Network Attack and Defense Practical Research on Vulnerability Exploitation and Privilege Elevation", I introduced MBSA separately to check the system vulnerability patching status. Microsoft officials searched for a long time, but could not find the software. There are some domestic websites that provide downloads of the software. For security reasons, they did not download it locally for testing. They accidentally found a small tool that can check and strengthen the Windows security baseline. Its implementation It turns out that it mainly detects Windows registry values ​​and then reinforces them. Software nameWindowsBaselineAssist
