Well... it didn't break anything. I guess that's a good sign.

Hello @TBugReporter , welcome to Ten Forums.
I had zero issues with this update. It hasn't "slowed" anything as far as I can see.
Most of us on here, use Macrium Reflect backup software religiously.
Then if MS has a bad day, WE don't suffer.
Sometimes, after a while, Windows 10 just gets all clogged up with things we've done, things we haven't done, etc.
That when the In-Place Upgrade comes to the rescue.
It more or less, does a repair install of Windows 10, without affecting our programs, drivers, and files.
Takes about 40 minutes total on my machine.

Lucky you.
No worries; "this machine" is like Number Seven in line as to most used and most important - plus I have everybody here avoid C:\ as much as possible and put their stuff on our server instead.
Actually, this is a bit of an experiment for this machine; a few weeks ago I pulled it out from a closet and upgraded it from W7, just to see how it'd handle it. Up until this update, it handled it pretty well.

Why am I not getting this update? It is not appearing on two of my computers. I even tried the Windows Update MiniTool and that does not pick it up either. The last one I got was the one released last February.

Never mind. I had the "Select when Preview Builds and Feature Updates are received" in GPEdit as "enabled" but with a "0" in the how many days to delay them. Apparently that messed things up. Maybe Windows Update thought it was still a "preview"? I disabled the setting and got the update right away. Why aren't those separate boxes?

Received this .NET update just now:
And interesting that for the first time (at least that I have noticed) it reboot twice to install.
