Windows 10: Crashes due to Hypervisor Error, Hypervisor Detected, Hyper-V not activated

Hello All,I have had my PC crash several times since I first got it with an issue regarding BugcheckCode 131073, or a Hypervisor error.In System Information, there is a line down the bottom saying "A hypervisor has been detected. Features required for Hyper-V will not be displayed." From this I assume there is an active hypervisor.As far as I know, Hyper-V is this only hypervisor program on my PC.I checked the Programs and Features tab to see if Hyper-V was activated, which it was not. Virtual Machine Platform and Windows Hypervisor Platform are also deactivated.My first thoughts are that th

Hyper-V-Hypervisor crash my PC when launching

Hello,

I'm encountering an issue regarding the new PC I bought, there is some strange comportments I don't understand.

At least once a day, my PC crash, I have a black screen with the sound playing, then the sound freeze and the PC reboot.

Looking in the event manager, at the time of the crash I see the start of Hyper-V-Hypervisor. some other logs about it like correcting CVE-2019-11091, CVE-2018-12126, CVE-2018-12127, CVE-2018-12130, then a warning "The hypervisor has not enabled mitigations for side-channel vulnerabilities for virtual machines because HyperThreading is enabled. To enable mitigations for virtual machines, disable HyperThreading." and two second after this "The system has restarted without shutting down properly first. This error can occur if the system becomes unresponsive, crashes or unexpectedly loses power."

Between them I have two volgmr error "Failed to create the memory image file due to an error while creating the image."

It seems to me Hyper-V-Hypervisor is about VM, but I'm not using any VM on my PC, why is it starting it?

When I try the command dism.exe /Online /Disable-Feature:Microsoft-Hyper-V to disable Hyper-V-Hypervisor I have the error 0x800f080c meaning Hyper-V-Hypervisor is not installed. Why does it start if it is not installed?

Each crash is preceded of the "Hyper-V-Hypervisor is starting" log, and each "Hyper-V-Hypervisor is starting" is followed by a crash.

Could you help me?

Thanks

 

How to start Hyper-V Hypervisor and then end it?

Hi!

I tried Windows Phone Emulator in Hyper-V.
It reports that Hyper-V Hypervisor is not running error.

So, How to start Hyper-V Hypervisor?
And also - how to stop Hyper-V Hypervisor? I need it.

No matter of solution, I accept also writing into Windows registry - I'm not newbie, but I never used Hyper-V.
Q is for this: I need to be sure when is Hypervisor on or when is off - for controlling system.

Even after Uninstalling Hyper-V - msinfo32 shows "A hypervisor has been detected"

Hi,

I'm running into a weird issue on my Lenovo Z51 laptop. Its equipped with an intel i7 processor and is running Windows 10 Pro (Build 14393).

I had Hyper-V installed on this laptop with all kinds of VMs running for a while. Then I got a VMware license and decided to uninstall Hyper-V. I uninstalled Hyper-V by going to "Turn Windows Features on or off", unchecking all options under Hyper-V and
then rebooting the machine on the prompt. After the reboot, I installed VMware but when I try to start the VMs, it gives me an error that Hyper-V is still running.

In the "Turn Windows Features on or off", the box for Hyper-V is unchecked. However, when I look at msinfo32 it still says>>

"A hypervisor has been detected. Features required for Hyper-V will not be displayed."

Coreinfo.exe says the same thing:

Intel(R) Core(TM) i7-5500U CPU @ 2.40GHz

Intel64 Family 6 Model 61 Stepping 4, GenuineIntel

Microcode signature: 00000021

HYPERVISOR * Hypervisor is present

VMX - Supports Intel hardware-assisted virtualization

EPT - Supports Intel extended page tables (SLAT)

I did a lot of hunting and already tried the below assuming some corruption:

"SFC /scannow" & reboot,

"dism /online /Cleanup-Image /RestoreHealth" & reboot

"bcdedit /set hypervisorlaunchtype off & reboot

None of these worked.

Why does it say the hypervisor is present when I have uninstalled Hyper-V ? What can I do to fix this and run VMware ?
