Hyper-V is the hypervisor built into Windows: it lets you create virtual machines without extra software. Microsoft states that there is no Hyper-V download: it is an optional Windows feature, which only appears if the edition and the hardware allow it. When Hyper-V is missing from the list, greyed out, or Hyper-V Manager cannot be found, the cause is almost always one of those below.
Observe before acting
Two checks are enough to find the cause in most cases.
- The Windows edition: Settings > System > Activation, the edition is shown at the top of the page.
- The hardware requirements: open PowerShell or Command Prompt and type:
systeminfo.exe
Scroll down to the Hyper-V Requirements section.
| What you see | Most likely cause | Step |
|---|---|---|
| Home edition | Hyper-V not available on this edition | Step 1 |
| A Hyper-V line in systeminfo says No | Virtualization disabled in BIOS/UEFI or incompatible processor | Step 2 |
| Pro or Enterprise edition, all lines Yes | Feature simply not enabled yet | Step 3 |
| systeminfo says "A hypervisor has been detected" | Hyper-V (or a feature that depends on it) is already running | Step 3, point 4 |
| VirtualBox or VMware stopped working since | Conflict between hypervisors | Step 4 |
Step 1: check the Windows edition
When to use it: Hyper-V is completely missing from the features list.
Microsoft is explicit: the Hyper-V role can't be installed on Windows 10 Home or Windows 11 Home. The documentation lists Windows 11 Pro or Enterprise.
Expected result: after upgrading to the Pro edition, Hyper-V appears in Windows features.
Rollback: upgrading to a higher edition is a purchase: first check that Step 2 will not block you.
Step 2: check hardware virtualization
When to use it: a line in the Hyper-V section of systeminfo says No, or the Hyper-V checkbox is greyed out.
According to Microsoft, Hyper-V requires a 64-bit processor with SLAT (Second Level Address Translation), hardware-assisted virtualization (Intel VT or AMD-V) enabled in BIOS/UEFI, hardware-enforced Data Execution Prevention (XD bit on Intel, NX bit on AMD) and at least 4 GB of memory.
Expected result: every line in the Hyper-V section says Yes.
Rollback: the virtualization option is disabled in the same place in the BIOS/UEFI.
The same requirement blocks WSL 2: if you also get error 0x80370102, see Error 0x80370102 when installing WSL 2 on Windows 11.
Step 3: enable Hyper-V
When to use it: Pro or Enterprise edition and requirements at Yes.
Expected result: Hyper-V Manager appears in the Start menu after restarting.
Rollback: clear Hyper-V in the same window, or:
Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V
Step 4: VirtualBox or VMware stopped working since Hyper-V
When to use it: Hyper-V is running and another virtualization app no longer starts its virtual machines, or switches to a slow mode.
Microsoft states that this behavior is by design: only one software component at a time can use the processor's virtualization extensions. When the Hyper-V hypervisor is running, third-party apps might not start their virtual machines or might fall back to a slower, emulated mode.
Expected result: after restarting, the other virtualization app works normally again.
Rollback: tick Hyper-V Hypervisor again and restart.
Warning: Microsoft states that some Windows protections depend on Hyper-V, including Memory Integrity and Credential Guard. Disabling Hyper-V for another app is therefore a security trade-off: do not do it "out of habit", only if you really need that other app.
Final check
- ☐ Pro or Enterprise edition.
- ☐ systeminfo: every Hyper-V line at Yes, or "A hypervisor has been detected".
- ☐ Hyper-V ticked in Windows features.
- ☐ Hyper-V Manager opens.
