W10 Anniversary Update manually loaded from MS website. This ain't an update, it's a new install. Takes a little over an hour.
You'll need to turn off everything again using Custom and delete Edge & Store from your taskbar. Other than some bloatware apps like Sports and Weather reappearing, I don't see any live tiles, ads, etc. on Start. Desktop is as I had it prior to invoking the update. So far, so good.
