Install Virtual Machine Platform in Windows 11 (Optional Features)

This guide shows you how to turn on the Virtual Machine Platform in Windows 11’s Optional Features. This enables you to run WSL 2 (Windows Subsystem for Linux), Android apps via Windows Subsystem for Android, and other virtualization-based tools. You’ll need administrator access to your PC, and your CPU must support virtualization (most modern ones do).

What You’ll Need

• A Windows 11 PC with administrator privileges.
• Virtualization enabled in your BIOS/UEFI (usually already on, but check if you run into issues).
• An internet connection (Windows may download files during installation).

Step-by-Step

1. Open the Start menu and type “Windows Features”. Click the result that says “Turn Windows features on or off” (the Control Panel applet).
2. In the Windows Features dialog, scroll down the list until you see Virtual Machine Platform.
3. Check the box next to Virtual Machine Platform. If you also plan to use WSL 2, check Windows Subsystem for Linux as well—it’s right above it.
4. Click OK. Windows will search for the required files and then ask you to restart your PC.
5. Click Restart now (or choose to restart later, but the feature won’t work until you do).
6. After the restart, the feature is active. You can verify it by running the command systeminfo in Command Prompt and looking at the “Hyper-V Requirements” section—it should show “A hypervisor has been detected.”

Common Mistakes

• Forgetting to restart: The feature only takes effect after a reboot. Some users try to use WSL immediately and get an error.
• Missing WSL 2: Enabling Virtual Machine Platform alone isn’t enough for WSL 2; you also need the “Windows Subsystem for Linux” feature and the WSL 2 kernel update (which you can get via wsl --update from an admin terminal).
• Virtualization disabled in BIOS: If your CPU supports virtualization but it’s off in the BIOS, the feature won’t work. You’ll need to reboot, enter BIOS (usually by pressing Del/F2 during startup), find the virtualization setting (often called Intel VT-x or AMD-V), enable it, and save/exit.
• Running an unsupported edition: Virtual Machine Platform is available on Windows 11 Home and Pro, but some very old builds may not have it. Make sure your Windows is updated.

Tips

• You can also enable the feature via PowerShell as an administrator with this command: Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform. This is handy if the GUI box is greyed out.
• If you only need the Virtual Machine Platform for WSL 2, you don’t need to enable the full Hyper-V role—just this feature and WSL.
• After enabling, check for Windows updates. Sometimes a cumulative update is needed for full compatibility.
• To disable later, simply uncheck the box and restart. Your virtual machines will stop working until you re-enable it.

Troubleshooting

• “Windows cannot find the files” error: This usually means your Windows installation is missing the feature files. Run sfc /scannow in an admin Command Prompt, then try again. If that doesn’t work, run DISM /Online /Cleanup-Image /RestoreHealth and retry.
• Feature installs but WSL still fails: Open an admin PowerShell and run wsl --update to install the WSL 2 kernel. Then restart your PC.
• “Virtual machine platform is not enabled” error in third-party apps: Double-check that the checkbox is ticked and the PC was restarted. Also verify virtualization is enabled in BIOS—you can check with Task Manager > Performance tab > CPU; it should show “Virtualization: Enabled”.
• Blue screen after enabling: This is rare but can happen if your PC has an incompatible driver. Boot into Safe Mode, disable the feature, then update your chipset drivers and try again.
• Feature is greyed out: This usually means your CPU doesn’t support virtualization or it’s disabled in firmware. Check your BIOS settings and make sure the CPU model supports VT-x/AMD-V.

Frequently Asked Questions

Do I need Hyper-V to use Virtual Machine Platform?

No. The Virtual Machine Platform is a separate feature that provides the necessary virtualization components for WSL 2 and Android apps. You do not need to enable the full Hyper-V role.

Will enabling this slow down my PC?

It uses a small amount of resources when idle, but only when a virtual machine is running does it consume significant CPU/RAM. Most users won’t notice any slowdown.

Can I use VirtualBox or VMware after enabling this?

Yes, but you may need to disable Hyper-V (which this feature relies on) to run older versions of those tools. Newer versions of VirtualBox and VMware are compatible with Hyper-V, but you might need to enable “Hyper-V” in their settings.

Is this the same as “Windows Hypervisor Platform”?

No. “Windows Hypervisor Platform” is a separate feature used by some emulators. Virtual Machine Platform is specifically for WSL 2 and Android. You can enable both if needed.

Do I need to enable this for Docker Desktop?

Docker Desktop on Windows can use WSL 2 backend, so yes, you’ll need Virtual Machine Platform and WSL. Docker will guide you through the setup if it’s missing.

Will this let me run Linux GUI apps?

Yes, with WSL 2 and a GUI app like WSLg (included in recent Windows 11 versions), you can run Linux GUI applications seamlessly.
