A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The setup package generally installs about 18 files and is usually about 96.25 MB (100,928,627 bytes). The installed file HostAppServiceUpdater.exe is the auto-update component of the program which is designed to check for software updates and notify and apply them when new versions are discovered.
