    NOTE: I'm using this in a RUN SCRIPT, so I hav the Parameters set to STRING, and in the RUN SCRIPT, I Create a list of options (TRUE & FALSE).

    In a normal script, you wouldn't do this... so modify for your deployment method.

    This was also intended to be used with ConfigMgr, if you're not, feel free to remove the $CMReboot & Corrisponding Function

    Installing Updates using this Method does NOT notify the user, and does NOT let the user know that updates need to be applied at the next reboot.  It's 100% hidden.
