Heretofore, except for Build 10240, we've always had the watermark; it lets us know which Insider build we're using.
We've also been told that in order to continue receiving Insider builds, we do nothing, but if we want to stick with RTM, we have to opt out of the Insider Program.
In order to opt out of the Windows 10 Insider Program, you should go into Settings>Update and Security>Advanced Options>click on "Stop Insider Builds". This will remove you from the Insider Program; however, you'll need to roll back to RTM. I saw the instructions to do that earlier (in the Windows 10 News/Build 10525 Available) but didn't think to save them, since I want to be an Insider.
