[wix-users] Avoid Bundle Resume After Reboot

[Rob Mensching]

A custom BA could decide to immediately exit post restart.

Yes, Burn does handle Restart Manager messages.

Thanks Blair!

I'm going to educate myself in WM_QUERYENDSESSION. Based on messages I've seen in bundle logs I guess that burn might handle WM_QUERYENDSESSION itself too. Is that a correct guess?

This still will not protect us against automatic resume after a system crash but perhaps we can limit automatic resume to just system crashes.
