I seem to not be receiving updates to Windows anymore

No idea why, but my 1709 x64 system seems to no longer install most updates to Windows. I got four updates on February 13, 2018, but they're all for Microsoft Office. Prior to that, I have one update for Flash that was installed on February 7, 2018 (KB4074595). Updates to Windows on my system exist that are older than that, but they were installed on January 9, 2018 and earlier.

Do I need to clean out Windows Update? I've run the usual DISM and SFC commands, SFC reports no issues.

No, I gave up on third-party AVs quite awhile ago. Running only WD. I checked for the applicable registry key, and it's set.

I had opened a thread regarding KB4056892, because I didn't receive that update when I thought I should have. I then installed KB4056892 manually, then removed it much later due to a horrendous performance impact.

So my questions are:

1. Would not having KB4056892 block everything else?
2. Why didn't I get KB4056892 automatically? And since manually removing it, it has not been installed automatically either. (Does it get blocked from reinstallation after being manually removed? Not that Windows would even have tried.)

I went off half-cocked here. I've yet to run the troubleshooter. Sorry, have not slept in days.

Same here ,Win10x64,1709 .
Had to download latest 2 cumulative updates manually , from the MS-site . Installed perfectly however.
Still wondering why not offered by WUS , the regkey is present ( Quality Compat )
Only got KB890830 ( monthly update).

I ran both WU troubleshooters (which I guess were the same thing, invoked from two different locations). Each time, it said there were pending updates. I opted to apply the "fix", then the troubleshooter said at the end that I had merely checked for pending updates. I guess I'm the crazy one who thinks there's a difference between "there are updates pending" and "there may be updates pending".

Then I ran the WU reset batch file available on this site, and rebooted. Checked for updates, and it found nothing.

Is there some other troubleshooting avenue I should follow, now that I've blown away the list of installed updates and can't even reference that?

I'm guessing the next suggestion will be for me to spend inordinate amounts of time reconstructing my Windows installation by either doing a "refresh" or installing anew.

Ok, so I did already ( downloaded from the MS-site and installed , without any problems) .
If I understand you well ,it should have been fixed now, by installing latest KB4074588 .
Will see what happens next month...............
( thanks for the advice )

Will see , can use a backup also I guess ( from januari )..............
