To reply to both your questions:
More Cowbell:
You can place a shortcut in your startup folder to The Launcher to have it start on windows boot-up.
The big advantage to using this is that you can connect the keyboard and press a cancel key to cancel the shutdown and return to windows for maintenance.
This program was written for a dedicated(?) arcade machine that doesnt normally have the keyboard attached.
+_+:
Yes, you can have some frontends shutdown when finished, but the front end I use, GLaunch cant do that, unless you write a bat file to do it for you.
The bat file will work, but The Launcher gives you a neat "shutdown screen" that you can design yourself. Using MSPaint, you can select the color of the shutdown screen and even paste pictures onto it. Gives your arcade that personal touch that you gave it when you built it, or restored it.
