To check on system services that are currently running - run WMI -- #53 -

Windows Management Instrumentation (WMI) - (Windows 10, 8.1, 8, 7, Vista)

You can run the HTML version - https://www.sysnative.com/SysnativeTutorials/wmi/batch/service_h.bat

Or you can run the TEXT version - https://www.sysnative.com/SysnativeTutorials/wmi/batch/service_t.bat



Another WMI goodie - detailed listing of system drivers - WMI #61 - Windows Management Instrumentation (WMI) - (Windows 10, 8.1, 8, 7, Vista)

I know that one WMI command/ batch file provides installed apps/programs, but I cannot seem to locate it at this time.
