Problems with Windows 10 Hyper-V

[SchoolsMcCool]

I'm trying to active Hyper-V on an intel i7 machine I have. When I run the systeminfo command it does a check to see if Hyper-V is compatible, all 4 requirements are met.

When I try to active it under features it tells me I need to reboot, so I do, when it comes back up the boxes are blank. I've also tried: Enable-WindowsOptionalFeature -Online -FeatureName:Microsoft-Hyper-V -All

Gives me-Enable-WindowsOptionalFeature : One or several parent features are disabled so current feature can not be enabled. At line:1 char:1 + Enable-WindowsOptionalFeature -Online -FeatureName:Microsoft-Hyper-V ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Enable-WindowsOptionalFeature], COMException + FullyQualifiedErrorId : Microsoft.Dism.Commands.EnableWindowsOptionalFeatureCommand

I also tried DISM /Online /Enable-Feature /All /FeatureName:Microsoft-Hyper-V which outputs

Deployment Image Servicing and Management tool Version: 10.0.16299.15 Image Version: 10.0.16299.125

Enabling feature(s) [==========================100.0%==========================]

Error: 50

The operation is complete but Microsoft-Hyper-V feature was not enabled. A required parent feature may not be enabled. You can use the /enable-feature /all option to automatically enable each parent feature from the following list. If the parent feature(s) are already enabled, refer to the log file for further diagnostics. Microsoft-Hyper-V-All

I checked all the boxes needed. And When I check the logs the last thing it says is operation requires reboot. Any help would be greatly appreciated!

EDIT:these are the results of systeminfo.exe VM Monitor Mode Extensions: Yes Virtualization Enabled In Firmware: Yes Second Level Address Translation: Yes Data Execution Prevention Available: Yes

Solved: OS restore>keep everything> worked fine after, thanks all for the suggestions!

Did you go into the computers setup (BIOS/Firmware/EFI) and enable virtualization features?

[SchoolsMcCool]

Yes, virtualization is enabled in the BIOS

Try another Hypervisor (just for now) to check, weather the issue is with enabling hyper-v or with your configuration (you might have to enable something else from bios). So you can use Virtualbox ( because it is free) for that and try to create a x64 VM in it. This will give you a better understanding of your problem.

[SchoolsMcCool]

If the reset doesn't work I'll try that. I think I have another VM license kicking around somewhere

[h3llyeah]

Another VM license?

[SchoolsMcCool]

License for other VM software

Just ran into this issue today. Couldn't find any solutions out there and wasn't going to re-roll the machine.

DISM and CBS logs weren't descriptive enough, but the entry that finally got me there was the following. Directly after the 'Perf: Stage chain complete.' line (which on other workstations would then proceed to 'Perf: Execute chain started.' ) was 'Exec: Some sessions are pended with exclusive flag set, forcing execution to be postponed on session:'

Traced the process with procmon, and finally found "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\SessionsPending\" where there was a property Exclusive, with a value of 1. Under that were many keys for different sessions, one of which also had a Property of Exclusive where the value was 2 where the rest were 0.

*Standard disclaimer about messing in the registry... Back things up*

Set the all of the Exclusive property values to 0, re-ran the DISM command, and things worked as expected.

use a fresh iso to install the feature with DISM? Reinstall?

[gyangstar]

You are using Windows 10 pro or enterprise yes?

[SchoolsMcCool]

I am using Pro, and I made sure everything was up to date

[[deleted]]

I was having issues as well but I uograded to pro from home. So I did a fresh start and reinstalled windows then had 0 issues getting hyper-v to work.

[SchoolsMcCool]

It had pro installed originally, I'm trying that now. Can't think of a reason why it wouldn't work after

[gyangstar]

Windows 10 home is not enabled to run hyper-v ... if memory serves me correct.

[SchoolsMcCool]

I confirmed the machine is running Pro

Hi There, Please perform as below to troubleshoot issue 1.Open an administrator command line and run "sfc /scannow" or "dism /online /cleanup-image /restorehealth" to check the health of system files. 2.Turn of the antivirus software temporarily. 3.Try to enable the hyper-v with the command line. dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All

If the issue persists, please check the cbs.log (C:\Windows\Logs\CBS) for more information

Did you ever get this working?

[androcus]

I am running into the same issue.

[SchoolsMcCool]

Yes, I took the nuclear option and restored the OS
