How to Disable Hyper-V and Windows Sandbox to Improve Android Emulator Performance

Certain Android emulators, such as BlueStacks, may experience performance issues or fail to start if virtualization technologies like Hyper-V and Windows Sandbox are enabled on your computer. This guide explains how to disable these technologies to enhance emulator performance.

The Issue

Hyper-V and Windows Sandbox are virtualization technologies provided by Microsoft that can be incompatible with some Android emulators. When enabled, these technologies can consume system resources needed for the emulators to function properly.

Steps to Disable Hyper-V and Windows Sandbox

1. Open Windows Features

   • Press Windows + R to open the Run dialog.
   • Type optionalfeatures and press Enter to open the Windows Features dialog.

2. Disable Hyper-V

   • In the Windows Features list, locate Hyper-V.
   • Uncheck the box next to Hyper-V to disable it.

3. Disable Windows Sandbox

   • Scroll down in the Windows Features list to find Windows Sandbox.
   • Uncheck the box next to Windows Sandbox to disable it.

4. Apply Changes

   • Click OK to apply the changes. Windows will process the disabling of these features.
   • Once the process is complete, you will be prompted to restart your computer. Click Restart now for the changes to take effect.

Verifying Hyper-V and Windows Sandbox are Disabled

After restarting your computer, follow these steps to confirm that Hyper-V and Windows Sandbox have been disabled correctly:

1. Check Hyper-V

   • Open PowerShell with administrative privileges (search for "PowerShell" in the Start menu, right-click, and select "Run as administrator").
   • Type the following command and press Enter:

     powershell
     Get-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All
     

   • The status should indicate that the feature is disabled.

2. Check Windows Sandbox

   • Similarly, in PowerShell, type:

     powershell
     Get-WindowsOptionalFeature -Online -FeatureName "Containers-DisposableClientVM"
     

   • The status should indicate that the feature is disabled.

Disabling Virtualization in BIOS/UEFI

If you need to disable virtualization at the BIOS/UEFI level, follow these steps:

1. Restart and Access BIOS/UEFI

   • Restart your computer and press the appropriate key (such as F2, F10, DEL, or ESC) to enter BIOS/UEFI during startup.

2. Disable Virtualization

   • In the settings menu, look for an option related to virtualization, such as "Intel VT-x", "AMD-V", or "Virtualization Technology".
   • Disable this option.
   • Save the changes and exit BIOS/UEFI.

Conclusion

By following these steps, you will disable Hyper-V and Windows Sandbox, freeing up system resources and improving the performance of Android emulators on your computer. This will allow you to use emulators like BlueStacks without compatibility issues related to these virtualization technologies.
