I don't even understand why we need such an updater.
1 major -> plus 1-2 minor releases within ~12 months.
I can already see people complaining about "how to roll back, my skin/addon/feature/settings/configuration/databases/whatever isn't working anymore".
To be honest, I hope this winsparkle update feature can be disabled or is disabled by default. Or get this functionality directly in Kodi as a simple "yes/no" dialog.
In my case, my HTPC is running Kodi as shell replacement, windows updates are disabled by default and it's completely controlled with a remote. It always annoys me if some software/driver package starts displaying update notifications and I have to get up to take the keyboard/mouse to close that damn dialogs.
