Bob, I think it confirms us that the problem most likely is not inside SimShaker Sound Module, which relys on Windows CLR (Common Language Runtime) system. Since .Net Framework (a CLR-based platform) is now embedded in Windows 10, I suggest that one cannot easily remove and reinstall it. I think Windows 10 "refresh" feature would have a chance to fix the issue. Another option could be to try to roll back to a some recent Windows restore point.
This is just my guess. Administration and recovery of Windows on users ' computers is beyond my competence.
