My machine is HP EliteBook 8540w which supports Hyper-V as far as I know and I have enabled it in BIOS. However, I am receiving the following error when trying to start emulator for Windows Phone apps in Visual Studio 2015:
Windows Phone Emulator is unable to start because the hypervisor is not running.
The more detailed screen shot follows:
According to my i7-720QmCPU specs, it supports VT-d
So what is the reason for it being unable to start the emulator on my machine?
Update:
I also checked using the BIOS settings using coreinfo tool with the results as in the following picture:
Update:
Following stijnvangaal's comment, I ran the following command as administrator and rebooted.
'bcdedit /set hypervisorlaunchtype auto'
But, in the wake of next run I faced the following Window ("Virtual machine service not running")
Then, I started this (by clicking the link on the message box):
Under, action menu, I clicked "start service" and then ran the application again in visual studio. Success? Not yet unfortunately, ending up in this (feeling desperate):
I had the same issue :
1 - I disable the Hyper V mode in the Windows Feature :
Go to ‘Programs and Features’.
Select Turn Windows Features on or off.
Deselect Hyper-V and click OK.
2 - Restart the computer
3 - Enable Hyper V again in the Windows Feature.
And it works !
Hope it help :)
Just disable Hyper-V on "Programs and Features" (if it is enabled). Then restart computer and turn it on again. Problem solved for me

I am trying to develop a new driver based on minispy code. I have successfully install minispy on my windows 11 (Surface computer) But i am trying to install the driver also on a window 10 (HP) and a Windows 11 dev (VM created with hyper-V) but it doesn't work... I have found the base code in this link : https://github.com/microsoft/windows-driver-samples/tree/main/filesys/miniFilter/minispy
after that i build it in Realease mode with visual studio 22 17.1.7 and i tried to install it by right-clicking on the minispy.inf and on install.
After this part I see minispy when i am running the command
driverquery
in my computers and VM, but when i am trying to start the service by running in an administrator command prompt
net start minispy
I get this result on my VM and my windows 10 computer (translate form french) :
error system 127
the procedure is unfindable
I don't really know what are the differences and I am feeling kind of lost here... If someone can help me i would be very happy!
I'm running Windows 10 with WSL2. I'm using VSCode with the Remote - WSL extension to open the files from my wsl file system.
When I boot my Windows laptop, and open VSCode I get the following error:
When I perform a wsl.exe --shutdown in PowerShell, and restart Docker Desktop, Everything works fine. But I have to do this after every laptop restart.
Remote WSL extension version: v0.51.4
Visual Studio Code version: v1.51.1
Windows version: 10.0.19041 Build 19041
Someone any idea?
I have had this problem several times, and I have found that on Windows 10 20H2 one of the two options described below solves the problem.
Network reset
This option can make you lose your network configuration, so use it with discretion and read every warning. You can perform this task by going to Settings > Network & Internet > Status. There you need to click on the option "Network reset" after that, you can start the network reset by clicking on "Reset now" Picture of Windows 10 20H2 status section. Then you will need to wait some minutes until your PC is restarted automatically and try to execute Visual Studio Code under WSL2 again.
Reset Windows
This option is dangerous as it will remove either all your files and programs or all your installed programs. You select what you want to remove before starting the reset process. This option can be performed by going to Settings > Update & Security > Recovery. Then you have to click on the button "Get started" on the section "Reset this PC" and follow the instructions provided by the reset tool Picture of Windows 10 20H2 recovery section. After your Windows is reset, you will have to configure your WSL again because all your WSL files will be lost when executing this operation.
After installing Xamarin studio and Xamarin android player along with Oracle VirtualBox. I have created demo code and installed Nexus 4 (kitkat) virtual device in Android player but after running application Xamarin Android player gets started but got following window with error.
This worked for me:
Network Connections -> Right click VirtualBox Host-Only Network -> Properties -> Enable (or Disable then Enable) "VirtualBox NDIS6 Bridged Networking Driver"
I found another question similar to the current question. see it Here
If you are using windows 10 then you need to have latest version of virtual box installed. you can get it from Virtual Box Downloads page.
I hope it helps.
Sigh. For reasons, I am running a windows xp virtual box in ubuntu. In this instance of windows there is an express (node) server running. Everything works fine, except that occasionally windows crashes or the virtual box freezes (perhaps after being left idle for several days). I would like to restart the virtual box (and node server) programmatically when this happens. The actual restarting of the virtual box from linux seems attainable, but I can't figure out how to get windows to run "node .../server.js" on startup! I tried putting the command in C:\AUTOEXEC.bat, and it did not start when I restarted the computer. I know I'm asking for trouble with a 10 year old OS but it's what I have to work with. Any thoughts?
Try scheduling in as a task in the task scheduler.
Tasks get executed when their triggers are satisfied, and in this case you can use the 'at startup' trigger, as described here:
http://technet.microsoft.com/en-us/library/cc748841.aspx
At startup
This trigger causes the task to run when the computer starts up. The only settings for this trigger are the advanced settings described in the Advanced Settings section below.
Look out though, that information wasn't tailor-made for XP, but should do it for you.
I actually just got it working. I put a batch file in start/programs/startup that CD'd to the right directory and then ran node.
I have this error message:
The windows phone emulator requires Hyper-V. Your PC is missing the

I cannot run my project on windows 8 phone emulator since days. I searched on internet, still I couldn't solve my problem.

Can anyone help me?
My computer features:

2- turn on hyper-v from windows
At the Start Screen, swipe the right hand side of the screen and select the Search Charm.
Type turn windows features on or off and select that item.
Select and enable Hyper-V.
If Hyper-V was not previously enabled, reboot the machine to apply the change.
I formatted my os from windows 8 pro to windows 8 enterprise and I solved my problem easily.I know it is not a logic solution but it worked.
In order to run Windows Phone 8 emulator you need to enable Hyper-V technology in the BIOS of your PC. See the detailed article on how to do this.
First you must turn on hyper-v from bios and then turn hyper-v from windows featured list restart and then will work ..
