How to disable Hyper-V in Windows?

Genymotion Desktop does not work well alongside Hyper-V at this time: it makes VirtualBox fall back to software virtualization which causes start up errors, extremely long booting time, major slowdown or stability issues.

Therefore, we highly recommend disabling Hyper-V when using Genymotion Desktop.

Step 1: Disable all Hyper-V feature

1. Go to Control Panel → Programs → Turn Windows features on or off

2. Uncheck Hyper-V in Windows feature:

   

3. Click OK

4. Windows Feature will apply the changes and ask you to restart. Click Restart Now to reboot the PC and apply the changes.

   

Also, make sure that the following features are disabled:

• Windows Subsystem for Linux 2 (WSL2)
• Windows Sandbox
• Virtual Machine Platform
• Windows Hypervisor Platform

Step 2: Disable Memory Integrity

Even though you have explicitly disabled Hyper-V, Windows 11 has several features that silently use the Hyper-V hypervisor in the background, which can prevent VirtualBox from accessing the hardware virtualization capabilities. One of those feature is the Memory Integrity security feature from the Core Isolation security measures.

To disable Memory Integrity:

1. Open Windows Security
2. Go to Device Security > Core isolation details
3. Turn Memory Integrity off
4. Reboot your PC when prompted

Step 3: Verify that Hyper-V is properly disabled

Open a PowerShell terminal and run the following command:

systeminfo | findstr -i "hyper-v requirements"

If Hyper-V is disabled, you should get the following output:

Hyper-V Requirements:          VM Monitor Mode Extensions: Yes
                               Virtualization Enabled In Firmware: Yes
                               Second Level Address Translation: Yes
                               Data Execution Prevention Available: Yes

Otherwise, Hyper-V is still enabled.

If you already followed instructions 1. and 2., and Hyper-V is still active, try following this guide to completely disable Hyper-V manually.
