The following error comes when I start a Machine.
The VBoxStartup.log
contains this entries.
f0c.10d8: supR3HardenedWinVerifyCacheProcessWvtTodos: 0 (was 0) fWinVerifyTrust=1 for '\Device\HarddiskVolume2\Windows\System32\winmmbase.dll'

This occurred after windows update. I'm running version 4.3.30 r101610 which I updated recently. The problem exists in previous two releases also (tested).
Right-click on the VirtualBox executable file. Choose Properties, and go to the Compatibility tab. Click on Run compatibility troubleshooter or just check the Run this program in compatibility mode for field. Save your changes, and run the program with admin rights.
Go to explorer, right-click C:\Program Files\Oracle\VirtualBox\drivers\vboxdrv\VBoxDrv.inf
and select Install
This will reinstall the VirtualBox kernel driver. After that VMs should once again start as expected.
