I had exactly the same problem as you, tried everything, but the solution is really easy:

  1. Open network center
  2. Change adapter settings
  3. Right click your Virtualbox host-only adapter and select Properties
  4. Enable "Virtualbox NDIS6 Bridget Networking Driver" (if it's disabled - if it's not, see next)

If the checkbox in step 4 was disabled, VB should work just fine now (no reboot needed). Otherwise repeat steps 3-4 for every network adapter you have (Ethernet, WiFi...) and always uncheck the NDIS6 checkbox -> apply -> check it again -> apply.

Hope this helps - worked for me on 2 different machines (it seems that this is caused by last Windows 10 update - thanks Microsoft for wasting another 4 hours of my life).

  • Thank you for saving (at least!) 4 hours of my life! The same Windows update had been in a failed-install state for a couple months, and when I finally fixed that sufficient for it to finish installing I was rewarded with this error. ;)

  • Thank you very much. Same problem here but linked to Vagrant not being able to pull up any VM anymore. Solved as you described :) Jan 21, 2016 at 5:14
  • Absolutely incorrect answer cannot believe this is being suggested! The HOST-ONLY adapters (Virtualbox/VMware) DO NOT BRIDGE anything - they are HOST ONLY! Enabling BRIDGING on them is incorrect. Don't believe me? Install VMware and look at it's adapters the BRIDGING adapter DOES need it enabled - the HOST ONLY does not and should not. If you need it - you have something mis-configured.
