Problem with the MsJet40.dll released with the Windows 10 KB4566782 Update

I'd urge you to use the Feedback command from within Access itself with all the details: Access version, bitness, build, is Access both front-end and back-end (if not front-end then what is, similarly for backend), exact steps to reproduce the issue, what changed (if you know) - when did it previously work, and be sure to include your email address so they can follow-up if need be.

Good luck.
