Running a virtual machine (VM) gives you a complete, isolated computer environment inside your existing machine. You can test software, run a different operating system, experiment with system configurations, or set up a safe sandbox for browsing suspect files — all without affecting your main installation. Windows 11 Pro includes Hyper-V, Microsoft’s own hypervisor, which provides enterprise-grade virtualisation without needing any third-party software.
Hyper-V is exclusive to Windows 11 Pro (available from GetRenewedTech for £18.99) — it is not available on Windows 11 Home. This guide covers everything from enabling Hyper-V to creating and managing your first virtual machine.
What Is Hyper-V and How Does It Work?
Hyper-V is a Type 1 hypervisor, meaning it sits between the hardware and the operating system. Unlike Type 2 hypervisors (such as VirtualBox or VMware Workstation) that run as applications inside Windows, Hyper-V gives virtual machines more direct access to hardware resources, which results in better performance — particularly for I/O-intensive workloads.
When Hyper-V is enabled, your physical Windows installation actually runs as a privileged virtual machine (called the Management OS or Root Partition) alongside the VMs you create. This architecture is extremely stable and is the same technology used in Windows Server environments.
System Requirements
Before enabling Hyper-V, verify that your system meets the requirements:
- Processor: 64-bit processor with Second Level Address Translation (SLAT), which is standard on any CPU manufactured after 2010
- RAM: 4 GB minimum, though 8 GB or more is strongly recommended if you plan to run VMs alongside regular work
- Virtualisation: Intel VT-x or AMD-V must be enabled in BIOS/UEFI. On most modern systems this is enabled by default, but on older machines you may need to enter BIOS settings and enable it manually
To check if your system supports Hyper-V, open Command Prompt and run systeminfo. At the bottom of the output, look for the Hyper-V Requirements section.
Enabling Hyper-V
Hyper-V is a Windows feature that needs to be turned on before first use. The quickest method is via PowerShell (run as Administrator):
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -AllAlternatively, go to Control Panel > Programs > Turn Windows features on or off, tick Hyper-V (including all sub-components), click OK, and restart when prompted. After the restart, you will find Hyper-V Manager in the Start menu.
Creating Your First Virtual Machine
Open Hyper-V Manager. In the right-hand Actions pane, click New > Virtual Machine. The New Virtual Machine Wizard guides you through the setup:
- Name and Location — give the VM a descriptive name and optionally change where the VM files are stored. If you have a second fast drive (SSD), store VMs there.
- Generation — choose Generation 2 for modern operating systems (Windows 8.1+, recent Linux distributions). Generation 2 VMs use UEFI boot and support secure boot, and are faster than Generation 1.
- Assign Memory — allocate RAM. Enable Dynamic Memory to allow Hyper-V to adjust RAM allocation based on demand, preventing the VM from monopolising memory when idle.
- Configure Networking — connect the VM to a virtual switch (create one first if needed via the Virtual Switch Manager in Hyper-V Manager). An External switch connects the VM to your physical network; an Internal switch creates a network between VMs and the host only.
- Virtual Hard Disk — create a new VHD or VHDX file. VHDX is preferred as it supports larger sizes and is more resilient to power failures. The default dynamically expanding disk grows only as large as the data inside it, saving host disk space.
- Installation Options — point to an ISO file for the operating system you want to install.
Installing an Operating System
Start the VM by double-clicking it in Hyper-V Manager and clicking Start. The VM will boot from the ISO you specified. Install the operating system as you would on a physical machine. After installation, install Hyper-V Integration Services if they are not installed automatically — on Windows VMs, these are included in Windows Update; on Linux VMs, use the linux-virtual package for your distribution.
Snapshots for Safe Experimentation
One of the most powerful features of Hyper-V is the checkpoint (snapshot) system. Before making any risky change — installing software, applying updates, running untested scripts — create a checkpoint via the right-click menu in Hyper-V Manager. If anything goes wrong, revert to the checkpoint and the VM returns to its previous state instantly. This makes VMs ideal for software testing, development, and security research.
Enhanced Session Mode for Better Integration
Enable Enhanced Session Mode (View > Enhanced Session) for a better VM experience: it allows clipboard sharing between host and VM, audio redirection, and the ability to use USB devices within the VM. This requires the VM to be running Windows with Remote Desktop Services enabled, but is straightforward on modern Windows installations.
Common Use Cases
- Software testing: Install new software in a VM before deploying to production machines
- Development environments: Run Linux alongside Windows for cross-platform development
- Legacy application support: Run Windows 7 or 10 VMs for applications that do not support Windows 11
- Security sandboxing: Open suspect email attachments or test downloaded software in an isolated VM
- Training environments: Create VMs pre-configured with specific software for consistent training setups
Hyper-V makes all of this possible at no extra cost beyond Windows 11 Pro. At £18.99 from GetRenewedTech, it is one of the most cost-effective ways to add enterprise-grade virtualisation capability to any Windows machine.
