If you are running Windows 11 Pro, you already have a fully capable virtualisation platform sitting on your machine doing nothing. It is called Hyper-V, it is built directly into the operating system, it costs nothing extra, and most people who would benefit from it have no idea it is there.
Hyper-V lets you run complete, isolated operating systems inside a window on your existing PC. A full copy of Linux. An older version of Windows. A sandboxed environment for testing software you do not trust. Each one runs in complete isolation from your main system, completely separate from your files, your settings, and anything else on the machine.
Here is what it is, why it is useful, and how to get it running.
What a Virtual Machine Actually Is
Before getting into Hyper-V specifically, it is worth being clear on what a virtual machine is, because the concept sounds more complicated than it actually is in practice.
Your PC has a processor, RAM, storage, and a graphics output. A virtual machine is a software layer that tricks an operating system into thinking it has all of those things, when in reality it is sharing them with your actual machine. You allocate some of your RAM and some of your storage to the virtual machine, and the software running inside it behaves as though it is running on real dedicated hardware.
From inside the virtual machine, Windows or Linux or whatever you have installed looks and behaves completely normally. From outside it, on your actual desktop, it appears as a window you can maximise, minimise, or close like any other application. When you close it, the virtual machine pauses or shuts down. When you open it again, it resumes exactly where it left off.
The critical detail is isolation. Whatever happens inside a virtual machine stays inside it. If you install something that turns out to be malware, it cannot reach your real system. If you experiment with settings and break the virtual machine completely, your actual PC is completely unaffected. You simply roll the virtual machine back to a snapshot you took before things went wrong.
What Hyper-V Is
Hyper-V is Microsoft's hypervisor, the technical term for the software layer that creates and manages virtual machines. Microsoft has been shipping it as part of Windows Server since 2008, and it has been built into the Pro and Enterprise editions of Windows for consumer use since Windows 8.
The reason this matters is that most people who want to run virtual machines reach for third-party tools like VirtualBox or VMware because they do not know Hyper-V exists. Both of those are excellent tools, but Hyper-V has the advantage of being already there, free as part of your Windows licence, and deeply integrated with the operating system in ways that give it some advantages, particularly for running Windows guests.
What You Can Do With It
Try Linux without committing to anything. The most common use case for someone new to virtual machines is curiosity about Linux. With Hyper-V you can install Ubuntu or any other Linux distribution in a virtual machine, try it out properly for as long as you want, and delete it when you are done without any of it touching your actual Windows installation.
Run old software that does not work on Windows 11. Legacy applications that require Windows 7 or Windows XP will not run on Windows 11 directly. In a virtual machine running the appropriate older Windows version, they work fine.
Test software you do not fully trust. If you need to run an executable from a dubious source, or just want to see what a piece of software does before committing to installing it on your real machine, a virtual machine is the right place to do it. Whatever it does is contained.
Development and testing environments. Developers use virtual machines to test how their software behaves in a clean environment, on different operating systems, or with different configurations, without affecting their working machine.
Checkpoints. Hyper-V includes a snapshot feature called Checkpoints. You take a snapshot of a virtual machine's state at a moment in time, do whatever you want with it, and if something goes wrong you restore the snapshot. The virtual machine reverts to exactly how it was. This is invaluable for testing anything where you might want to undo changes.
Before You Start: Requirements
Hyper-V requires Windows 11 Pro or Enterprise. It is not available on Windows 11 Home, which is the most common version sold on consumer laptops. If you are on Home, you would need to upgrade your Windows edition or use VirtualBox instead.
Your processor needs to support hardware virtualisation, which is a feature called Intel VT-x on Intel chips or AMD-V on AMD chips. Every processor made in the last decade supports this, but it sometimes needs to be enabled in your BIOS. You also need at least 4GB of RAM, and practically speaking 8GB or more makes the experience significantly better since the virtual machine shares your physical RAM.
To check whether your system supports Hyper-V, open Command Prompt and type systeminfo. Scroll to the Hyper-V Requirements section at the bottom of the output. If everything shows Yes, you are ready. If Virtualization Enabled in Firmware shows No, you need to enable it in your BIOS first.
How to Enable Hyper-V
1: Open Windows Features
Press Windows and R, type optionalfeatures and press Enter. The Windows Features dialog opens. Alternatively, search for "Turn Windows features on or off" in the Start menu.
2: Enable Hyper-V
Scroll down the list and find Hyper-V. Tick the checkbox next to it. This automatically selects both Hyper-V Platform and Hyper-V Management Tools underneath it. Also tick Windows Hypervisor Platform while you are there.
Click OK.
3: Restart
Windows will install the required components and prompt you to restart. Click Restart now. After the reboot, Hyper-V is active.
Creating Your First Virtual Machine
After restarting, search for Hyper-V Manager in the Start menu and open it. The interface looks slightly old-fashioned, but it is straightforward once you know where to look.
1: Create a Virtual Switch
Before creating a virtual machine, you need to set up a virtual network switch so the VM can connect to the internet. In Hyper-V Manager, click Virtual Switch Manager in the right panel. Select New virtual network switch, choose External, and click Create Virtual Switch. Give it a name like External Switch, make sure it is bound to your real network adapter, and click OK.
2: Start the New Virtual Machine Wizard
Click New in the right panel, then Virtual Machine. The setup wizard opens.
Give the virtual machine a descriptive name. Choose where to store its files. The default location is fine for most people.
3: Choose Generation 2
Select Generation 2 when prompted. Generation 2 supports modern UEFI firmware and Secure Boot and is the right choice for any operating system released in the last decade including all current versions of Windows and Linux.
4: Allocate Memory
Assign RAM to the virtual machine. For a general-purpose Linux installation, 4GB is comfortable. For a Windows 11 guest, give it at least 4GB and ideally 8GB if your machine has enough. Enable Dynamic Memory to let Hyper-V adjust the allocation based on what the VM actually needs.
5: Connect to the Network
Select the virtual switch you created earlier from the dropdown. This gives the VM internet access through your machine's connection.
6: Create a Virtual Hard Disk
Create a new virtual hard disk. Set the size based on what you plan to do with the VM. For a basic Linux install, 40GB is plenty. For a Windows guest with applications installed, 80GB or more is more comfortable.
7: Attach an ISO
Select Install an operating system from a bootable image file and browse to an ISO file. Download Ubuntu from ubuntu.com or grab a Windows ISO from Microsoft if you have a licence. Point Hyper-V at that file.
Click Finish.
8: Start the Virtual Machine and Install
Double-click your new virtual machine in the list. A connection window opens. Click Start. The virtual machine boots from the ISO and the operating system installation begins. Complete it as you would on a real machine.
Checkpoints: The Feature That Changes Everything
Once your virtual machine is running, take a checkpoint immediately after setting it up the way you want it. Right-click the VM in Hyper-V Manager and select Checkpoint. Give it a name like Fresh Install.
From this point, you can do anything to the virtual machine, install software, change settings, run things you are not sure about, and if anything goes wrong, right-click the VM and select Revert. It rolls back to the checkpoint instantly. You start again from a clean slate without reinstalling anything.
This is genuinely one of the most useful things about virtual machines in general and Hyper-V makes it easy to use.
Hyper-V vs VirtualBox
The main practical difference for everyday use is that Hyper-V is deeply integrated with Windows and tends to perform better for Windows guests. VirtualBox works on Windows Home and has better out-of-the-box support for some Linux features. If you are on Windows 11 Pro and primarily want to run Windows or mainstream Linux distributions, Hyper-V is the simpler choice since it is already there.
One important note: running Hyper-V can cause compatibility issues with some other virtualisation software, including older versions of VMware and certain Android emulators, because Hyper-V takes control of the hardware virtualisation features that these tools also need. This is worth knowing before enabling it if you use any of those tools regularly.
Final Thoughts
Most Windows 11 Pro users walk past Hyper-V every day without knowing it is there. For anyone who wants to try a different operating system safely, test software in isolation, maintain a sandboxed environment for sensitive tasks, or simply learn how virtual machines work, it is one of the most accessible entry points available. Free, capable, and already installed. It just needs to be turned on.
Frequently Asked Questions
Does Hyper-V work on Windows 11 Home?
No. Hyper-V is only available on Windows 11 Pro, Enterprise, and Education editions. If you are on Windows 11 Home, VirtualBox is a free alternative that works without any edition restrictions.
Will enabling Hyper-V slow down my main Windows installation?
Enabling Hyper-V does not noticeably affect day-to-day performance when no virtual machines are running. When a VM is running, it uses a portion of your RAM and processor, so having more RAM helps. On a machine with 16GB of RAM you can run a comfortable virtual machine alongside normal work without feeling it.
Can I run Windows 11 inside Hyper-V?
Yes. You need a Windows 11 licence and an ISO file. Microsoft offers free evaluation ISOs of Windows 11 for testing purposes. The performance is good and Hyper-V handles Windows guests particularly well given that both are Microsoft products.
What is the difference between a checkpoint and a backup?
A checkpoint is a snapshot of the virtual machine's current state stored alongside the VM. It lets you revert quickly to a previous state. It is not a backup. If the physical drive containing the VM files fails, checkpoints are lost along with everything else. For genuine backup, copy the VM files to a separate drive periodically.
Can I run Linux in Hyper-V?
Yes. Ubuntu, Debian, Fedora, and most mainstream Linux distributions install and run without issues under Hyper-V. Hyper-V has good Linux integration services that handle display scaling, clipboard sharing, and file transfer between the host and the Linux guest.
