This is a real quandary. On one hand you want to keep your Windows 10 system up to date for protection from exploited vulnerabilities. On the other hand, remember the old adage "If it ain't broke, don't fix it."
But then you have to wonder about the quality of the Microsoft updates.
Some people have made a career out of pointing out all of the foibles, I think Woody Leonhard does thorough research and has a capable staff but I never run into the problems he reports on. I guess I'm just lucky.
Clearly there are many Windows users impacted by problematic updates. And Microsoft struggles with explaining what causes them.
And here's an example of just how confusing this problem is.
Yep, 2 articles on KB4535996. The first one (archive.is) saying that it fixes "search and printing problems" and the second one (archive.is) saying that it "causes freezes, installation issues." Admittedly, for now, this is an "optional" update but it demonstrates the underlying issues with Windows updates.
What to do?
Take a system image backup. Cross your fingers. Apply them.
