SQL 2016 SP2 CU9 update: Failed to verify the Authenticode signature, Signature verification of SQL Server DLLs will be skipped. Genuine copies of SQL Server are signed.

I am seeing this error after the update:

Genuine copies of SQL Server are signed. Failure to verify the Authenticode signature might indicate that this is not an authentic release of SQL Server. Install a genuine copy of SQL Server or contact customer support.
