3. Storage: Use SSD storage for the virtual disk if possible
4. Snapshot: Create a snapshot after successful installation for easy recovery
5. Disable Windows Hypervisor: Follow the steps shared below.

To address performance issues and reduce perceived “slowness” in your virtual machine, you can disable the Windows Hypervisor. Please note that this action may affect other virtualization software on your system (such as Hyper-V, Windows Sandbox, or WSL2) and could slightly reduce security. Proceed only if you are certain your primary virtualization tool (e.g., VMware, VirtualBox) does not require the Windows Hypervisor.

Prerequisites

• Administrator Access: You must have administrator privileges on your computer.
• Backup: It is recommended to create a system restore point before making these changes.

Step-by-Step Instructions

1. Open an Administrator Command Prompt.
   • Click the Start menu or press the Windows key.
   • Type cmd or “Command Prompt.”
   • In the search results, right-click on Command Prompt and select Run as administrator.
   • If prompted by User Account Control (UAC), click Yes to continue.
2. Disable the Hypervisor.
   • In the Administrator Command Prompt window, carefully type the following command and press Enter:
     bash bcdedit /set hypervisorlaunchtype off
   • You should see the message: “The operation completed successfully.”
3. Disable Hypervisor-Enforced Code Integrity (Optional but Recommended).
   • Next, type or paste the following command and press Enter:
     bash reg add "HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity" /v "Enabled" /t REG_DWORD /d 0 /f
   • You should see the message: “The operation completed successfully.”
4. Restart Your Computer.
   • Close the Command Prompt and restart your PC for the changes to take effect.
