I asked about this previously:
As recommended, I turned off Automatically check for updates. I presumed that the next update I would receive would be a stable channel update. (Perhaps a mistaken presumption on my part?) Instead, the next thing that happened a couple weeks later was another beta update that downloaded and installed itself automatically. This is an actual screen cap as it happened (I deleted background imagery showing other open programs):
So how do I really disable beta updates? Do I have to downgrade to the current stable version? If I do that, will all my existing data be preserved?
Perhaps the next time you invite ordinary customers to join your beta program, you might consider explaining that while it's trivially easy to join the beta, it will take more effort to leave it. That way, your customers can make a more informed decision about whether to proceed.
