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 circulate on the third and fourth week of each month. They include fixes (not security fixes) and install only to those who click on "Check for Updates" in Windows Update.
Those users they are essentially beta testing the updates before releasing them in next month's Patch Tuesday "stable" updates. Patch Tuesday updates are called “B” updates, as they are released the second week of each month.
Updates C and D caused a lot of problems. For example, an "D" update recently caused blue screens in Microsoft's Surface Book 2. The problem of course appeared only 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 C information KB4476976 appears to have been thoroughly checked through 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 experiments with the "Check for Updates" button do not seem to satisfy users who want a stable operating system. For the majority, the distribution of untested patches without notice is not allowed, especially by a company the size of Microsoft.
