I would like to know how to change the Vista Start Menu power button function in the registry. I prepare new Vista PCs and I need to change the Start Menu power button from the default Sleep to Shut Down. I know how to get to the feature in the Power settings, but a simple registry hack would save me a lot of time. Once I know what to change, I can create a reg file to do it quickly for me. Does anyone know where these settings are held?
