Sometime back, I was under the impression that Icon owners had to use "Release Preview" in order to get Win 10 updates. I had been a Insider Slow User and switched to Release Preview several months ago. I am presently running version 10.0.14393.105. I got an update just yesterday. I just tried switching back to Slow Insider but when I check for updates, it tells me that I am up to date. How do I get the Anniversary Update?
