MMC crash in windows 10 - certificate

Question

On my Windows 10, mmc.exe crashes when I try to add the certificate snap-in. When I click "Ok" after having added the snap-in (computer account, local computer) the message: "Microsoft Management Console has stopped working" and I am offered a debug option.
There are no further error messages.
I have tried to run "sfc /scannow" and found nothing to repair.

Answer 1

The MMC is crashing because of the SqlManager.dll from SQLServer 2014 RTM (2014.0120.2000.08 ((SQL14_RTM).140220-1924 ))

So update the SQL Server to latest Service Pack and Update Hotfix Rollup. Import the uninstall .reg to disable dump creation and app verifier.
