After Update from 4.0.16 to 4.1.16: "Cannot access the kernel driver" Message

Exactly the same problem and solution as described here:
"It seems at least on my system two device drivers are not installed by the installation program. After a manual installation of these drivers everything works again. Go to C:\Program Files\Oracle\VirtualBox\drivers\USB\filter Select VBoxUSBMon.inf and click the right mouse button. Then pick Install. Go to C:\Program Files\Oracle\VirtualBox\drivers\vboxdrv Select VBoxDrv.inf and click the right mouse button. Then pick install. VirtualBox should now work again as expected."
If you could please fix this update problem.
