How to Fix Slow VMware Performance on Windows 11

Introduction:

If you're experiencing slow VMware performance on your Windows 11 machine, you're not alone. Many users have reported lagging virtual machines or general performance degradation when running VMware on Windows 11. This issue is often related to Hyper-V, a feature of Windows that can interfere with VMware's performance.

Why is VMware Slow on Windows 11?

The root cause of VMware running slow on Windows 11 often stems from Hyper-V being pre-configured or enabled. Hyper-V is Microsoft's native hypervisor, and when it's running on your system, it can conflict with VMware's hypervisor, causing your virtual machines to underperform.

Solution: Disable Hyper-V to Improve VMware Performance

To resolve this issue, you can disable Hyper-V on your Windows 11 host machine. Here's how:

1. Turn Off Hyper-V:

• Open the Command Prompt as an Administrator.

  • To do this, search for "cmd" in the Start menu, right-click it, and select Run as Administrator.

• In the Command Prompt window, type the following command:

  bcdedit /set hypervisorlaunchtype off

• Press Enter to execute the command.

• After running the command, restart your system to apply the changes.

This will disable Hyper-V and prevent it from interfering with VMware, which should restore performance.

2. To Re-enable Hyper-V (Optional):

If you ever want to return to Hyper-V mode, it's easy to do so. Simply open the Command Prompt as an Administrator again and run the following command:

bcdedit /set hypervisorlaunchtype auto

• Press Enter, and restart your system to re-enable Hyper-V.

3. Disable Memory Integrity (If Needed):

In some cases, you might also need to disable Memory Integrity (a feature of Core Isolation) for VMware to function properly. To disable it, follow these steps:

• Go to Windows Security.
• Click on Device Security.
• Under Core Isolation, select Core Isolation details.
• Toggle Memory Integrity to Off if it's enabled.

This step may not always be necessary, but it's worth checking if you're still experiencing performance issues.

4. Run VMware as Administrator:

For better performance and fewer permission-related issues, run VMware as an administrator.

• Right-click on the VMware shortcut on your desktop or in the Start menu.
• Select "Run as administrator" from the context menu.
• If prompted by User Account Control (UAC), click "Yes" to allow it.
• Optional – To always run VMware as administrator:
  • Right-click the VMware shortcut and choose "Properties".
  • Go to the "Compatibility" tab.
  • Check the box that says "Run this program as an administrator".
  • Click "Apply" and then "OK".

Conclusion

By disabling Hyper-V, you can significantly improve the performance of VMware on Windows 11. Whether you're using VMware for development, testing, or running virtual machines for any other purpose, this simple fix can resolve slow performance and help your system run smoothly. If you want to re-enable Hyper-V later, you can always follow the same steps to turn it back on.
