This is a System Information script that uses Windows Management Instrumentation instead of a .dll. The script is pretty straight forward, just load and click channel or status to use.

Under System Info, you will see Public & Private. Public will display your system info to the current channel. Private will echo your system info back to the active screen. All will display everything and the other menu selections should be exactly what they say.

Example Output:
