>>>Hi Bass: Well, no, maybe I didn't state it correctly. The Clean Install from ISO file worked and installed b14393.5 and subsequently auto-updated to b14393.10==the latest version just fine. The issue I'm stating is that none of my 5 machines would do an install to any Anniversary Update build that's been released starting on last Tue. Aug. 2nd, when attempting to get the download through Windows Update. The issue will be for users who are on W10 going back to v1511 b10240.x and v1511 b10586.x released last July 29th 2015, and then are attempted to UPDATE their existing W10 system, they cannot do it;Your install media could be bad/corrupted. Get the media creation tool and redownload the ISO. Then do another clean install.
