Delete Hyper-V Virtual Machine in Windows 10

Windows 10, Windows 8.1 and Windows 8 come with Client Hyper-V so you can run a supported guest operating system inside a Virtual Machine. Hyper-V is Microsoft's native hypervisor for Windows. It was originally developed for Windows Server 2008 and then ported to Windows client OS. It has improved over time and is present in the latest Windows 10 release as well. Here are a number of ways to delete an existing Hyper-V virtual machine.

Note: Only Windows 10 Pro, Enterprise, and Education editions include the Hyper-V virtualization technology.

What is Hyper-V

Hyper-V is Microsoft's very own virtualization solution that allows creating virtual machines on x86-64 systems running Windows. Hyper-V was first released alongside Windows Server 2008, and has been available without additional charge since Windows Server 2012 and Windows 8. Windows 8 was the first Windows client operating system to include hardware virtualization support natively. With Windows 8.1, Hyper-V has got a number of enhancements such as Enhanced Session Mode, enabling high fidelity graphics for connections to VMs using the RDP protocol, and USB redirection which is enabled from the host to VMs. Windows 10 brings further enhancements to the native hypervisor offering, including:

1. Hot add and remove for memory and network adapters.
2. Windows PowerShell Direct – the ability to run commands inside a virtual machine from the host operating system.
3. Linux secure boot - Ubuntu 14.04 and later, and SUSE Linux Enterprise Server 12 OS offerings running on generation 2 virtual machines are now able to boot with the secure boot option enabled.
4. Hyper-V Manager Down-level management - Hyper-V manager can manage computers running Hyper-V on Windows Server 2012, Windows Server 2012 R2 and Windows 8.1.

Virtual Machine Generations in Hyper-V

When you create a new virtual machine with Hyper-V,  you can choose between two generations of your virtual machine.

Generation 1 is a legacy BIOS/MBR machine. It supports 32-bit operating systems. Its virtual hardware is similar to hardware which was available in all previous versions of Hyper-V.

Generation 2 comes with modern features like UEFI and secure boot, but it doesn't support 32-bit OSes. It features extra features, such as PXE boot, Boot from a SCSI virtual hard disk
Boot from a SCSI virtual DVD, and more.

Note: If you are going to install a 32-bit guest OS in your VM, then choose Generation 1. Once a virtual machine has been created, you cannot change its generation.

Hyper-V Virtual Machine Files

A virtual machine consists of several files, such as configuration files, and virtual disk files that store the guest operating system for a machine. By default, Hyper-V stores all files for your virtual machines on your system partition. You might want to store them on another disk or partition. Last time we reviewed how to set a new default folder for virtual disks. The same can be done for configuration files.

Note: When you create a virtual machine in Hyper-V Manager, you are able to specify a folder to store its files.

If you need to remove a virtual machine, you can use either the Hyper-V Manager tool, or PowerShell. When you delete a VM, the virtual machine's configuration file will be removed, but it does not delete any virtual hard drives (.vhdx). The checkpoints will be deleted and merged into the virtual hard disk files after the VM is deleted.

To Delete a Hyper-V Virtual Machine in Windows 10,

1. Open the Hyper-V Manager from the Start menu. Tip: See How to navigate apps by alphabet in Windows 10 Start menu.  It can be found under Windows Administrative Tools > Hyper - V manager.
2. Click on your host name on the left.
3. In the middle pane, click on your virtual machine in the list to select it.
4. If it is running, then turn off the VM.
5. In the right pane, click on Delete... under Actions.
6. Alternatively, you can select Delete from the right-click context menu of the machine, or press the Del key in the list of the virtual machines.
7. Confirm the operation.

You are done. The VM will be renamed. Now, you close the Hyper-V Manager app.

Alternatively, you can rename a Hyper-V VM with PowerShell.

Move Hyper-V Virtual Machine with PowerShell

1. Turn off the virtual machine you want to rename.
2. Open PowerShell as Administrator. Tip: You can add "Open PowerShell As Administrator" context menu.
3. Execute the next command to see the list of your machines and their generations.

    Get-VM

   

4. Type and execute the following command: Remove-VM "VM name" -Force.
5. Substitute the VM name portion with the actual virtual machine name  from the step 3.

For example,

Remove-VM "Win10" -Force

That's it.
