hyper-v not running (sometimes)

I have searched through the forums to resolve the "Hypervisor is not running" error. I know that I have everything set correctly because it does run.

My problem is that to make it run I have to change the DEP setting from "DEP for all programs" to "essential" and back, with restarts, to get the hypervisor and the emulator to start every single time.

Thanks for the reply!

I know this won't help, but I don't see anything unusual in the logs, NS is set to AlwaysOn and the Hypervisor is set to Auto.

Hi Sardus,

According to your description, the hyper-v  works sometimes and sometimes it doesn`t .Changing the DEP settings will make it work .
When did this issue occur ?Have you made any midifications to the machne or installed any third party software before the issue ?

To use the hyper-v ,the DEP is necessary .I suspect there is a  third party software conflict here .
When the issue occur ,we can use the follow command to check the status of the DEP .
"wmic OS Get DataExecutionPrevention_Available"
If the output is true ,DEP is available .

We also need to run "wmic OS Get DataExecutionPrevention_SupportPolicy" to check the present DEP policy .
2 OptIn (default configuration)
3 OptOut DEP is enabled for all processes.
1 AlwaysOn
0 AlwaysOff
When the issue occured ,we can perform a clean boot to have a troubleshoot .

Is there any unusual log recorded in the Windows Logs \Application ,system  of Event Viewer?
