Many third-party virtualization applications don't work together with Hyper-V. Affected applications include VMware Workstation and VirtualBox. These applications might not start virtual machines, or they may fall back to a slower, emulated mode.
These symptoms are introduced when the Hyper-V Hypervisor is running. Some security solutions are also dependent on the hypervisor, such as:
Device Guard
Credential Guard

Determine whether the Hyper-V hypervisor is running
To determine whether the Hyper-V hypervisor is running, follow these steps:
Many virtualization applications depend on hardware virtualization extensions that are available on most modern processors. It includes Intel VT-x and AMD-V. Only one software component can use this hardware at a time. The hardware cannot be shared between virtualization applications.
To use other virtualization software, you must disable Hyper-V Hypervisor, Device Guard, and Credential Guard. If you want to disable Hyper-V Hypervisor, follow the steps in next two sections.
How to disable Hyper-V
You can disable Hyper-V Hypervisor either in Control Panel or by using Windows PowerShell.
Disable Hyper-V in Control Panel
To disable Hyper-V in Control Panel, follow these steps:
In Control Panel, select Programs and Features.
Select Turn Windows features on or off.
Expand Hyper-V, expand Hyper-V Platform, and then clear the Hyper-V Hypervisor check box.
Disable Hyper-V in PowerShell
To disable Hyper-V by using Windows PowerShell, follow these steps:

In some scenarios, you may need to uninstall Hyper-V on your Windows machine. For example, VMware Workstation and Hyper-V are not compatible when installed on the same machine. The same issues occur with other type 2 hypervisors like VirtualBox.
Besides its performance impact on other hypervisors, many users report increased performance in games and emulators after disabling Hyper-V. So, if you're not planning to run heavy-duty workloads on your VMs, it might be a good idea to disable Hyper-V and switch to VirtualBox or VMWare Workstation.
Enable or Disable Windows Virtualization: Launch the Windows Features tool:Click the Search icon.Type Turn Windows features on or off in the search field.
As mentioned above, you can not simultaneously use the Hyper-V role and VMware Workstation within the same Windows Server instance. However, you can run another instance of Windows Server on a Hyper-V virtual machine that can host VMware Workstation nested.
Two, hyper-v is a virtual machine tool from Microsoft; Hyper-V If you are using multiple operating systems on your computer, this is what allows that. If your not, disable it, you don't need it.
Find the process vmwp.exe that has the GUID of your VM in the User name column.Kill this VM process (End Task). Similarly, you can find and stop a hung virtual machine process on a Hyper-V host using the Process Explorer tool. Run Process Explorer as administrator and click Find Handle or DLL (or press Ctrl-F);
But sometimes you may no longer need Hyper-V on a machine. This can be the case when you want to run another type 2 hypervisor on the same Windows machine, for example, VirtualBox or a VMware Workstation. Hyper-V can cause issues and you will have to disable and uninstall it.
Hyper-V specifically provides hardware virtualization. That means each virtual machine runs on virtual hardware. Hyper-V lets you create virtual hard drives, virtual switches, and a number of other virtual devices all of which can be added to virtual machines.
The biggest drawback of Hyper-V is that it is not widely cross-platform compatible with other operating systems. While you can deploy Linux VMs on Hyper-V advanced features, like those found in System Center Virtual Machine Manager (SCVMM), rely on Microsoft and Windows functionality.
Performance is negatively affected because workloads can't take advantage of the NUMA optimizations. To learn more about the maximum configurable components in Hyper-V, see Plan for Hyper-V scalability in Windows Server.
Open your task manager by using Ctrl+Shift+Esc keys. If your processor supports hardware virtualization, you will see virtualization as Enabled along with the other details, or otherwise disabled. If it does not support virtualization, you will not see Hyper-V or virtualization mentioned in the task manager.
To disable Core isolation (HVCI): In the Windows Start menu, search Core isolation and press Enter to open your Device security settings.Toggle Memory integrity off and restart your computer.
