Not that I am tracking, I think you get pushed back down to the latest major build and still have to update the months between fixes even if not on Insider. I don't ever restore from Backups, just from experience the Apps act buggy because some of the settings are not backwards compatible to non-insider ring builds. Get to the current ring, remove all the bloatapps I don't use that they put on there anyways. Then I go the Store Library and select my apps and then set it down. It sounds like it would take longer but the times I have done it resulted in a much quicker turnaround doing it manually. Granted most of my stuff is sync'd on Onedrive including Music.
