Solution

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).

Thanks bro...but i uninstall windows updates after that i am getting this error. I created another host-only adapter after restart it's successfully running.

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 :)

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.

For me this worked askubuntu.com/a/1320895/792047
