Description

This module checks the AlwaysInstallElevated registry keys which dictates if .MSI files should be installed with elevated privileges (NT AUTHORITY\SYSTEM). The generated .MSI file has an embedded executable which is extracted and run by the installer. After execution the .MSI file intentionally fails installation (by calling some invalid VBS) to prevent it being registered on the system. By running this with the /quiet argument the error will not be seen by the user.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
