Filters drivers can sometimes cause performance issues and other bad things to happen on a server. The quickest and easiest way you can figure out what filters drivers are running is by using the fltmc.exe command. This command works on several versions of the Microsoft Windows operating systems.
1. Open up a PowerShell or cmd window with administrative privileges.
2. Run fltmc without any switches to get a current list of active filter drivers.
Below is a quick screenshot the switches that are available for the fltmc.exe command.
