The Hyper-V components are not enabled by default in Windows environments, probably because not all environments will be able to utilize virtualization, depending on their specific CPU limitations.

Install the Hyper-V role on Windows Server

Applies To: Windows Server 2016, Windows Server 2019

To create and run virtual machines, install the Hyper-V role on Windows Server by using Server Manager or the Install-WindowsFeature cmdlet in Windows PowerShell. For Windows 10, see Install Hyper-V on Windows 10.

To learn more about Hyper-V, see the Hyper-V Technology Overview. To try out Windows Server 2019, you can download and install an evaluation copy. See the Evaluation Center.

Before you install Windows Server or add the Hyper-V role, make sure that:

• Your computer hardware is compatible. For details, see System Requirements for Windows Server and System requirements for Hyper-V on Windows Server.
• You don't plan to use third-party virtualization apps that rely on the same processor features that Hyper-V requires. Examples include VMWare Workstation and VirtualBox. You can install Hyper-V without uninstalling these other apps. But, if you try to use them to manage virtual machines when the Hyper-V hypervisor is running, the virtual machines might not start or might run unreliably. For details and instructions for turning off the Hyper-V hypervisor if you need to use one of these apps, see Virtualization applications do not work together with Hyper-V, Device Guard, and Credential Guard.

If you want to install only the management tools, such as Hyper-V Manager, see Remotely manage Hyper-V hosts with Hyper-V Manager.

Install Hyper-V by using Server Manager

1. In Server Manager, on the Manage menu, click Add Roles and Features.

2. On the Before you begin page, verify that your destination server and network environment are prepared for the role and feature you want to install. Click Next.

3. On the Select installation type page, select Role-based or feature-based installation and then click Next.

4. On the Select destination server page, select a server from the server pool and then click Next.

5. On the Select server roles page, select Hyper-V.

6. To add the tools that you use to create and manage virtual machines, click Add Features. On the Features page, click Next.

7. On the Create Virtual Switches page, Virtual Machine Migration page, and Default Stores page, select the appropriate options.

8. On the Confirm installation selections page, select Restart the destination server automatically if required, and then click Install.

9. When installation is finished, verify that Hyper-V installed correctly. Open the All Servers page in Server Manager and select a server on which you installed Hyper-V. Check the Roles and Features tile on the page for the selected server.

Install Hyper-V by using the Install-WindowsFeature cmdlet

1. On the Windows desktop, click the Start button and type any part of the name Windows PowerShell.

2. Right-click Windows PowerShell and select Run as Administrator.

3. To install Hyper-V on a server you're connected to remotely, run the following command and replace <computer_name> with the name of server.

   PowerShell

   Install-WindowsFeature -Name Hyper-V -ComputerName <computer_name> -IncludeManagementTools -Restart  
   

   If you're connected locally to the server, run the command without -ComputerName <computer_name>.

4. After the server restarts, you can see that the Hyper-V role is installed and see what other roles and features are installed by running the following command:

   PowerShell

   Get-WindowsFeature -ComputerName <computer_name>  
   

   If you're connected locally to the server, run the command without -ComputerName <computer_name>.
