What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
To enable hardware virtualization, turn on the processor’s virtualization option in your PC’s UEFI/BIOS firmware, then verify it in Windows. If your goal is to run Hyper-V or another Windows virtualization feature, you may also need to enable that Windows component separately. Check the current status first: many Windows PCs already have virtualization enabled.
What hardware virtualization does—and what it does not do
Hardware virtualization is a processor capability that lets compatible software run virtual machines or other virtualized workloads. The UEFI/BIOS setting exposes that capability to the operating system and applications; it does not install a virtual-machine app or automatically enable every Windows virtualization feature.

Enabling it is not a guaranteed way to make a PC faster. Its benefit depends on the workload and the software you plan to use. The official setup and requirements guidance cited here does not promise a fixed performance improvement from changing the setting alone.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesCheck whether virtualization is already enabled
- Right-click Start and open Task Manager.
- Select Performance, then CPU.
- Check the Virtualization status. If it says Enabled, the firmware feature is on.
Intel notes that an Enabled status can appear while another hypervisor is already using virtualization; it is not necessarily an error. See Intel’s explanation of processor virtualization support.

Enable virtualization in UEFI/BIOS
Menu names and locations vary by PC and motherboard model, so there is no universal firmware path or reliable key to press on every device. Identify your computer’s manufacturer and exact model, and use its support instructions. Microsoft cautions: “Only change what you need to in the UEFI (or BIOS). Adjusting other settings might prevent you from accessing Windows.”
- Open Windows Recovery. In Windows 11, go to Settings > System > Recovery and select Restart now beside Advanced startup. In Windows 10, go to Settings > Update & Security > Recovery and select Restart now under Advanced startup.
- Restart into firmware settings. In the recovery menu, choose Troubleshoot > Advanced options > UEFI Settings > Restart. Your device may call this interface BIOS rather than UEFI.
- Find the processor virtualization option. On Intel systems, look for a label such as Intel Virtualization Technology or VT-x. On AMD systems, look for AMD-V or SVM. The manufacturer may use different wording or place the option in a different menu.
- Enable the setting and save. Use the firmware utility’s save-changes option, then allow the computer to restart. Avoid changing unrelated firmware settings.
- Verify in Windows. Return to Task Manager > Performance > CPU and confirm that Virtualization reports Enabled.
Microsoft notes that many Windows devices already have virtualization enabled, so you may not need to change firmware settings. Intel VT-x also requires support from both the processor and BIOS; a firmware toggle alone cannot add support to unsupported hardware. Intel explains this requirement in its processor virtualization support guidance.

Choose the right Windows component for your goal
Firmware virtualization and Windows virtualization features are separate. Enable only the Windows component your intended app or workflow requires.

|---|---|
| Third-party virtual machine or emulator | Check the app’s own host requirements. Turn on processor virtualization in firmware if the app requires it; the app may have additional requirements. |
| Windows Virtual Machine Platform | Open Start, search for Windows features, then select Turn Windows features on or off. Enable Virtual Machine Platform if your workflow calls for it, and restart if Windows requests one. |
| Hyper-V | Check your Windows edition and all Hyper-V hardware requirements. In Command Prompt or PowerShell, run systeminfo.exe and review the Hyper-V Requirements section. |
Microsoft’s Hyper-V requirements list Windows 10/11 Professional or Enterprise for enabling the Hyper-V role, along with a 64-bit processor, Second Level Address Translation (SLAT), VM Monitor Mode extensions, firmware-enabled hardware virtualization, and hardware-enforced Data Execution Prevention (DEP). Microsoft says all listed requirements must report Yes for the system to run the Hyper-V role. Its guidance recommends planning for at least 4 GB of RAM, with more memory preferable so Windows and running virtual machines have enough. That memory guidance is for Hyper-V, not a universal minimum for processor virtualization.

- Virtualization is already Enabled: Don’t toggle firmware settings just because an app reports an issue. Intel notes that another hypervisor may already be using the feature. Check the app’s specific error and requirements.
- No firmware option appears: Confirm the exact PC model and processor. Intel says VT-x support depends on both processor and BIOS; consult the computer or motherboard maker’s documentation. Some manufacturers may hide or restrict firmware options.
- Firmware says Enabled, but Hyper-V cannot run: Run
systeminfo.exeand check every item under Hyper-V Requirements. Virtualization support alone does not establish that the processor, Windows edition, memory, and other requirements are satisfied. - A non-Microsoft app still fails: Identify the Windows component and hardware capabilities it requires before changing additional settings. Requirements differ among virtual-machine apps and emulators.
For device-specific firmware steps, use Microsoft’s Enable Virtualization on Windows guidance and your computer or motherboard manufacturer’s support documentation.
