If you’re seeing the error “The VMSP service failed to start” in Windows 11, it typically appears when launching a virtual machine in Hyper-V or when starting virtualization-related components. This error prevents virtual machines from running and may be accompanied by additional messages in Event Viewer.
The VMSP service (Virtual Machine Service Provider) is part of Hyper-V and works alongside core virtualization services to manage virtual machine memory and state. When this service fails, it is usually due to disabled Hyper-V features, corrupted system files, virtualization settings in BIOS, or misconfigured Windows services.
If the VMSP service failed to start on your Windows 11 PC, follow the detailed troubleshooting steps below.
How to Fix “The VMSP Service Failed to Start” in Windows 11
Work through each solution in order. After completing a step, try starting the virtual machine again.
1. Restart Hyper-V Related Services
The VMSP service depends on multiple virtualization services.
- Press Windows + R.
- Type: services.msc
- Press Enter.
- Locate the following services:
- Hyper-V Virtual Machine Management
- Hyper-V Host Compute Service
- Double-click each service.
- Set Startup type to Automatic.
- Click Start if the service is not running.
- Restart your PC.
After rebooting, try launching your virtual machine again.
2. Enable Hyper-V Feature Properly
If Hyper-V is partially enabled, services may fail.
- Press Windows + R.
- Type: optionalfeatures
- Press Enter.
- Ensure the following are checked:
- Hyper-V
- Virtual Machine Platform
- Windows Hypervisor Platform
- Click OK.
- Restart your PC.
Enabling all required components ensures proper service initialization.
3. Enable Virtualization in BIOS/UEFI
If virtualization is disabled at the hardware level, Hyper-V services will not start.
- Restart your PC.
- Enter BIOS/UEFI settings (usually by pressing F2, Del, or F10 during boot).
- Locate Intel VT-x, Intel Virtualization Technology, or SVM Mode (for AMD).
- Enable it.
- Save changes and exit.
After enabling virtualization, boot into Windows and test again.
4. Run System File Checker (SFC)
Corrupted system files can prevent virtualization services from loading.
- Press Windows + S and search for Command Prompt.
- Right-click and select Run as administrator.
- Enter: sfc /scannow
- Press Enter.
- Restart your PC after completion.
Windows will repair corrupted files automatically.
5. Run DISM Scan
If SFC does not resolve the issue:
- Open Command Prompt as administrator.
- Enter: DISM /Online /Cleanup-Image /RestoreHealth
- Press Enter.
- Restart your PC after the scan completes.
This repairs deeper Windows image corruption.
6. Check Event Viewer for Specific Errors
Additional details may appear in logs.
- Press Windows + X.
- Select Event Viewer.
- Go to: Windows Logs > System
- Look for errors related to Hyper-V or VMSP.
The error code can help identify configuration or permission issues.
7. Disable Conflicting Virtualization Software
Third-party virtualization tools can conflict with Hyper-V.
If installed, temporarily disable or uninstall:
- VMware
- VirtualBox
- Android emulators
Restart your PC after removing conflicting software.
8. Reset Hyper-V Using PowerShell
Reconfiguring Hyper-V may resolve persistent service failures.
- Press Windows + X.
- Select Windows Terminal (Admin).
- Enter: Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All
- Restart your PC.
- Then run: Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All
- Restart again.
This reinstalls Hyper-V components.
9. Install Windows Updates
Outdated builds may contain virtualization bugs.
- Press Windows + I.
- Go to Windows Update.
- Click Check for updates.
- Install available updates.
- Restart your PC.
System updates often fix service-related issues.
Conclusion
The “VMSP service failed to start” error in Windows 11 is usually caused by disabled virtualization settings, incomplete Hyper-V installation, corrupted system files, or conflicts with third-party virtualization software. In most cases, enabling virtualization in BIOS and properly configuring Hyper-V resolves the issue.
By following the structured troubleshooting steps above, you should be able to restore Hyper-V functionality and start your virtual machines normally. If the issue persists even after reinstalling Hyper-V, deeper system corruption or hardware-level configuration problems may require further investigation.
