I think you have to set a policy on your computer(s) to disable the
restart manager, because as it says here:
https://msdn.microsoft.com/en-us/library/windows/desktop/aa372466%28v=vs.85%29.aspx

"Silent UI level installations always shut down applications and
services, and on Windows Vista, always use Restart Manager."

So you have to set the "DisableAutomaticApplicationShutdown" policy as
described here:
https://msdn.microsoft.com/en-us/library/aa368298%28v=vs.85%29.aspx
to "2".

But remember: preventing processes from restarting and expecting a
reboot but not automatically reboot leaves the system in an unstable
state because only *some* of the files got replaced, not all. I guess
that's why msi doesn't let you do this easily.
At least with an UI install, the user is aware of the problem - for
silent installs, the user would not know that and I guess that's why
it's not possible to do that.
