It hard to overstate the problems caused by Microsoft second, third and fourth September cumulative updates for all Windows 10 versions.
For example, Win10 version 1903, the latest and greatest, saw cumulative updates on Sept.
10 (KB 4515384), Sept.
23 (KB 4522016), Sept.
26 (KB 4517211) and Oct.
3 (KB 4524147, which some characterize as a super-early October cumulative update).
As Microsoft kept flinging buggy fixes at the zero-day problem known as CVE-2019-1367, customers kept complaining about problems with:Print spooler crashes — No, they weren''t fixed with the fourth cumulative update, KB 4524147, in spite of Microsoft assertions.
In fact, Mayank Parmar at Windows Latest documents complaints about KB 4524147 breaking PCs that were working after the third cumulative update, KB 4517211.
So we have separate printer bug reports for the second, third and fourth cumulative updates.

Yes, that the bug that is known to persist (reappear?) in the fourth cumulative update.
