Comment 2 for bug 858398

I have changes that will go into the next release that will hopefully make this a nicer experience. Rather than asking for or forcing a reboot after upgrade, the installer can take care of the upgrade for you. If it finds an uninstaller from a previous version, it goes ahead and stops the old executables, then uninstalls, then carries on with the new installer, which will then put you into a running state with the new U1 and no need to stop what you were doing.
