The real stinker this month, KB 4524244, rolled out the automatic update chute for four full days until Microsoft yanked it – leaving a trail of wounded PCs, primarily HP machines, in its wake. The other big-time bug in this month’s patches, a race condition in the KB 4532693 Win10 version 1903 and 1909 cumulative update installer, hasn’t been officially acknowledged by Microsoft outside of a blog post. But at least it’s well known and understood.
Folks running SQL Server and Exchange Server networks need to get patched right away.
