Once upon a time, install programs would shut down and restart windows without asking you. Nowadays, most of them ask whether you want to restart, or at least warn you that it is about to restart windows. But even now, some installers or patch programs would restart your computer without notifying you. This program tries to prevent that from happening. It runs as red exclamation mark in the system tray. Whenever a request to shut down windows is received, it will ask you whether to let it through.
