Sounds good but a couple of thoughts:
1. I seem to remember find issues with the original implementation of
CloseApplications with tray applications, might be worth making sure the new
code doesn’t break anything (in my case it was a VB6 application!)
2. What would happen if someone tried to kill a service? I can think of a
good reason to do this but it might be worth checking the outcome.

Subject: [WiX-devs] RFC: CloseApps extension enhancements.
I was using CloseApplications from the WixUtilExtension recently and found I
needed a bit more functionality than what is currently present.
Here's what I'm thinking about adding:
1. Add "EndSessionMessage" and "ElevatedEndSessionMessage" attributes - this
will more mimic the Restart Manager behavior where a WM_QUERYENDSESSION then
WM_ENDSESSION is sent. Those messages seem to be more in vogue that sending a
WM_CLOSE these days. I'm not planning to do it exactly like RM where all apps
are sent a query message before sending the end session messages. I'm just
going to do each message back to back (unless the query says don't try to end).
I'm doing this because I found some apps that got unhappy being told to close.
I'm not married to those attribute names.
2. Add "TerminateProcess" attribute - this will act similar to the existing
RebootMessage attribute but kill the process instead of scheduling a restart.
Killing processes is generally a bad thing but I've run into a couple customers
now that say that is the correct way to close their process that has no window.
I'm not married to that attribute name but "KillProcess" seemed a little
aggressive. <smile/>
3. (if I have time) Add a "Timeout" attribute - this will allow each
CloseApplication element to change the default wait when doing a close. Right
now the default is hardcoded to 5 seconds which seems reasonable, but if I have
time, I thought I'd allow it to be configurable.
Any questions, concerns, suggestions?
