As we have said in an earlier publication, Microsoft releases "C" and "D" updates to those who click "Check for Updates" in Windows Update.
Everyone who tries "Check for Updates" through Windows Update beta testers are automatically done.
From January 2019, however, Microsoft changed this one mode, and Type C updates are tested first by Windows Insiders.
As we have mentioned earlier, the C and D updates released on the third and fourth week of each month. They include corrections (not fixes security) and are installed only to those who click on “Check for Updates” in Windows Update.
These users actually test the beta updates before releasing the "fixed" Patch Tuesday updates next month. Patch Tuesday updates are called "B" updates, as they are released in the second week of each month.
Updates C and D caused too many problems. For example, an update “D” caused recently blue screens on Microsoft's Surface Book 2. The problem of course it only appeared to those who clicked on “Check for Updates.”
Naturally no one knows how many of those who check for updates know they are selecting unstable updates.
So the above news seems to be good, as this month for the C update KB4476976 detailed checks seem to have been done via the Windows Insider Release Preview ring:
It's not irrelevant. We just did a small change in our approach. 1809 is going to RP today and will be critical for helping kick start servicing. Slow was helpful in helping ID any show stopping bugs this time around.

The update is still a C update and will only be installed if you click Check for Updates, but this time it appears to have been tried by those who have chosen to try Microsoft products. We are talking about Windows Insiders who have chosen to be beta testers.
Microsoft should take drastic action after its fiasco October 2018 Update whose development resembled the bridge of Arta.
Microsoft's experimentation with the “Check for Updates” button seems to be failing to satisfy users who want a stable operating system. For the majority the distribution of untested patches without prenotice is unacceptable especially from a company the size of Microsoft.
