Seems now that a forced check for updates is updating to 1809

I guess that is what they call a Push Update?

... I went to check on my unupdated 1803 install and checked for updates and there it was.

This is to be expected now that the rollout has restarted. At present only a few machines will find 1809 when manually checking for updates. As MS gather more telemetry that number will increase. MS said that was the way it would happen here...

...For those advanced users seeking to install the update early by manually using “Check for updates” in settings, know that we are slowly throttling up this availability, while we carefully monitor data and feedback.

I have a "gut" feeling that MS opened the faucet up some more today.

I think you are right, I'm increasingly seeing Ten Forum members reporting they got it by manually checking. As yet I've only seen a couple of reports that may have got it automatically. I'm leaving a couple of machines on 1083, one running 24/7, to check when automatic delivery starts. So far neither see 1809 automatically (last automatic check was less than an hour ago).

fyi wushowhide.diagcab does not work anymore, it is not able to block 1809 permanently... afaik WuMgr should work on
