I like to use portable apps (on the system drive) because of the automatic update feature.
Some are even in Windows Autostart (CrystalDiskInfo...), which sometimes leads to the "App has not been propery closed"-message (not sure about exact english phrase).
(I think when shutting down Windows the PortableApp-Launcher sometimes gets closed before the app it is monitoring)
It is then starting to clean up and exits.
It would be so much more convenient, if it could just start the app anyway after cleaning up instead of just exiting.
Anyway, thanks for your work to provide all those nice portable Apps for us!
