Windows 10: Window sandbox fail to start 0x800706d9 (Hypervisor/Virtual Machine Support Driver element...

When I run the sandbox, error 0x800706d9 displayed


From the event viewer


The Container Manager Service service depends on the HV Host Service service which failed to start because of the following error:

The dependency service or group failed to start.


The HV Host Service service depends on the Hypervisor/Virtual Machine Support Driver service which failed to start because of the following error:

Element not found.


The Hypervisor/Virtual Machine Support Driver service failed to start due to the following error:

Element not found.

:)

 

Virtual Machine is not starting because Hypervisor is not running

Virtual Machine is not starting because Hypervisor is not running.

Any suggestion?

 

How to disable hypervisor after uninstalling Sandbox feature?

No, it's Pro version still unactivated. I just installed it on spare PC to get a look at Sandbox feature and what I can do with it.

Probably it would be easier if I just describe the steps I took:

1. Created ISO with media builder 1903

2. Installed from this on clean system, deleting and recreating all disk partitions

3. Created a local user account on first start, logged in with it

4. In windows features scrolled down to Windows Sandbox and checked only it, Hyper-V features are available but I didn't check them for install

5. Reboot

6. Did few tests with the sandbox app, ran couple of programs in it, confirmed for myself that it uses Hyper-V technology for virtualization (first symptom - any other 3rd party virtualization software won't run, same error as when Hyper-V feature is installed,
this is known problem with HV in windows 10)

7. Finished with tests, removed Windows Sandbox from Features. Hyper-V feature still wasn't enabled in list of features, only Windows Sandbox was.

8. Reboot

9. Logged in, discovered I still cannot run VmWare and hypervisor is still enabled.

Currently both Hyper-V and Windows Sandbox are disabled/not installed in Windows Features window but the virtualization is enabled on the system. So I think I need to manually 'switch it off' or something.

As I wrote earlier, maybe installing and uninstalling Hyper-V would help, I just thought maybe there is a fast way to disable it in command line or registry

 

How to disable hypervisor after uninstalling Sandbox feature?

Hi, maybe someone can suggest something beside installing and uninstalling hyper-v feature. I didn't have time to try it yet, don't currently have access to PC in question.

So, I installed win10 1903 and enabled that new Sandbox feature to see how it works. After the end of test I removed it, but hypervisor it installed is still enabled on system.

Task manager shows 'Virtualization: enabled', systeminfo says 'A hypervisor has been detected' and vmware player won't start.

So now I need to somehow manually uninstall this hypervisor, any ideas? Going through anything remotely connected to windows features (dism, powershell) is no go since Hyper-V feature isn't installed so there's nothing to uninstall
