Yes, Martin, agree. I had done that, as many others. Kicked it up to 17133/34, then opted out. I just was not comfortable that all the ET-call-home was gone, or Insider restrictions of some kind buried. I decided to restore my MR image of FCU and play it straight. Just me, I've got 6 flavors of this beast to play with, and didn't need it like that.
Is this KB showing in your Update History? It is on 2 I did, but not the third. 3rd one also had that "Retry" issue. Shows in Reliability History, but not Update History or Installed Updates. WINVER say 17134.5
You also get other updates slightly earlier - including driver updates, if that floats your boat - I disable driver updates but have not had any issues with the actual technical updates
Un-enrolling insider builds now and will be doing a fresh install of the RTM on Monday.
