Answer 1

Use a logoff or shutdown script to launch an exe? This can be set by Group Policy.

Of course, I hope you have a good reason (like my corporate build) to do this. As mentioned in comments, what are you tring to do please?

See response on WM_POWERBROADCAST message. Also take into account that your ability to prevent shut down can depends on OS (it seems on Vista and later there are additional capabilities).
