When Hyper-V does not work properly on Windows 10, you can troubleshoot and resolve it through the following steps: 1. Confirm the system is Pro, Enterprise or Education version, and make sure that the CPU supports virtualization technology and is enabled in BIOS/UEFI; 2. Manually enable the Hyper-V function, install relevant components through the control panel or PowerShell command and restart; 3. Check and uninstall possible conflicting software such as VMware or VirtualBox, turn off Sandbox and other Hyper-V-based functions, and confirm that the "Hyper-V Virtual Machine Management" service is running; 4. Use sfc /scannow and DISM tools to fix system file problems. The above steps are operated in sequence to resolve most Hyper-V failures.

Hyper-V sometimes does not work properly on Windows 10, which may be a problem with system settings, hardware support, or service status. To solve this problem, the key is to check several key links and check them one by one.

Make sure your system supports Hyper-V

Hyper-V is not supported by default in all Windows 10 versions. It is only available for Pro, Enterprise, and Education versions. The Home version does not support Hyper-V.

In addition, your computer CPU must support virtualization technology (Intel VT-x or AMD-V) and is enabled in BIOS/UEFI. You can confirm by:

• Open Task Manager → Performance tab → Check whether the Virtualization status is Enabled
• Use tools such as Core Isolation or third-party software such as Securable to detect

If these conditions are not met, Hyper-V will not be able to operate.

Enable Hyper-V feature

Hyper-V is turned off by default and needs to be turned on manually:

1. Open Control Panel → Programs → Enable or turn off Windows features
2. Check "Hyper-V", including two sub-items: "Hyper-V Platform" and "Hyper-V Management Tools"
3. After clicking "OK", the system will install components and prompt to restart

You can also use the PowerShell command to quickly turn on:

 Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

After executing the command, you also need to restart the computer before it can take effect.

Check for conflicting software and services

Some security software or virtualization tools (such as VMware or VirtualBox) may conflict with Hyper-V, causing them to fail to start.

You can try the following:

• Uninstall or disable virtual machine software such as VMware, VirtualBox, etc.
• Turn off Windows Sandbox and other Hyper-V-based features
• Check if the Hyper-V Virtual Machine Management service is running in Services

If you are not sure which programs may conflict, you can go to safe mode to test whether Hyper-V works properly.

Fix system file problems

Sometimes system files are corrupted, which can cause Hyper-V to fail to start. You can try to fix it using the system file checking tool:

1. Open PowerShell or Command Prompt as an administrator
2. Enter the following command:

    sfc /scannow

3. Restart the computer after completion

If SFC does not find any problem, you can also try the DISM tool to fix it further:

 DISM /Online /Cleanup-Image /RestoreHealth

This process may take some time, and try to start Hyper-V again after it is finished.

Basically these common solutions. Hyper-V problems are usually not caused by a single cause, so it is recommended to check them step by step in order. As long as the system supports, functions are enabled, and there is no conflict, it can be restored to normal in most cases.
