VirtualBox no acceleration on Windows 10 host
It is almost guaranteed that Hyper-V has been (re-)enabled.
Go to control panel and turn it off as per the photo.
Do make sure you have the latest VirtualBox as Windows 10 is not supported in versions before 5.x.
Update for more recent Windows 10 - if you disable Hyper V but have Windows Subsystems for Linux installed then you have to also disable that too.

After upgrading my host OS to Windows 10, I have noticed some problems with my guests so I looked around the settings and noticed that the number of CPUs and acceleration options are greyed out.. I didn't update the virtualbox nor did anything change with my guests since last time, so only I can think of is that the upgrade of host caused this.
Now I wonder if Win 10 introduced some fundamental changes that would somehow affect virtualization or is it only my problem?
VB version 5.0.1 Win10 as a host, Lubuntu as a testing guest (but all guests have the acceleration disabled in them)

-
Raven over 8 yearsWhat is the recommended version? 5.0.4 or 4.3.30 (both are marked as active development)
-
Ramhound over 8 yearsOnly one indicates specific support for Windows 10.
-
Raven over 8 yearsupgrading to 5.0.4 did not solve the issue (weren't the Win10 support related to guest as opposed to host which is my case?)
