Are there resources with summary information about problematic Windows updates?

Question

Windows

Based on another crooked update from Meltdown: a test group of 10 PCs absolutely did not react to the installation of KB4088878 / KB4088878 and the update was approved for all the others. The consequences are known to all.
I wondered if there is some specialized resource where summary information about problematic updates is collected?

Answer 1

There is! Oddly enough, this is the site of Microsoft itself :D. And no, I'm not kidding.
