I have made an earlier post, last week I believe, regarding this nightmarish update issue and I think my problem is similar to yours; however, my cum update numbers are a little different.  For instance, my initial problem stemmed from not being able to successfully install updates (v1709) numbered KB4088776 and KB 8058043 plus an update for Adobe flash player KB 4088785.  I have spent untold hours on the phone with Microsoft level 2 tech support and this issue is still unresolved.  Then, tonight, to add insult to injury, I got a notification that there were 4 MORE updates which supposedly downloaded and needed installing with a restart, which I did, and 3 out of 4 of these failed!  WTF!!!  So I still have a big RED X on the Windows Defender Shield down in the system tray.  So here's my question:  Can anyone solve these update problems in easy-to-understand steps in layman's terms, or not?

It happens on a fresh setup on the surface book 2.

Couldn't get help from MSFT even after trying for hours as well.

Even worse -- they dared to suggest their paid tech support.

Well, I am a paid client of their Microsoft Answer desk and it isn't helping me out with this issue.  Microsoft, are you reading this???
Same problem for me.  I uninstalled it and windows defender is starting properly again.
I was never able to install the Cumulative Update through Windows Update, This was on a fairly fresh Windows installation on a Surface Book 2.  I was able to install it with the standalone installer, however.  See Knowledge Base article and download link.
I was trying to do the suggested workaround which was uninstall the January cumulative update but my system won't allow me to uninstall cumulative updates.  I'm not a total novice but I don't understand how they give this as a workaround when uninstalling them isn't allowed.  What am I doing wrong?

I was able to get my system fully up to date by doing the following:

1. Download and install Cumulative update KB4088776
https://www.catalog.update.microsoft.com/Search.aspx?q=KB4088776

2. Reboot

3. Download and install Delta update KB4093112

https://www.catalog.update.microsoft.com/Search.aspx?q=KB4093112

4. Reboot

5. Run the Windows update

Hope this helps

They don't read their customers' response. Mostly, it is just volunteers who are given titles for kissing Microsoft's a__. You'll never get a response that will be helpful to your question.
Gohran writes clearly and well. Worked for me. 
I tried Gohran's method.  KB4088776 is listed as being already installed.  When I downloaded the Delta update KB4093112, my computer came up with a dialog window which said that it was not appropriate for my machine. (I chose the x64 version)
