The Virtualization-Based Security (VBS) feature comes into focus in Windows 11 and is enabled by default in newer systems.This feature is also present in Windows 10, but it takes up quite a bit of system resources.

If you experience slow game performance after upgrading to Windows 11, don't panic.If you've tried everything and nothing seems to work, then VBS might be the culprit behind your low framerate.So let's explore how to disable VBS and squeeze the most performance out of your system.

 

Does VBS really slow down performance?

PC Gamer and Tom's Hardware have an in-depth look at the performance degradation with VBS enabled.The results of both studies showed a performance drop of 5-25%.Games like Horizon: Zero Dawn and Shadow of the Tomb Raider saw massive FPS drops.

Surprisingly, the CPU and GPU frequencies remained the same.But the power consumption of these components is reduced.There hasn't been any detailed discovery yet as to what exactly caused it.However, if you want maximum performance in games and applications, VBS is likely to be in your way.

What would be the effect of disabling VBS on your system?

Virtualization Based Security (VBS) works with the Windows Hypervisor to create an isolated area of ​​memory.This isolated area securely stores login credentials, critical Windows security codes, and more. HVCI is a function that uses VBS to perform integrity checks on programs.

Simply put, when VBS is active, it is hard for attackers.Therefore, turning it off exposes you to kernel-level attacks.If you're someone who uses your own system for classified official work, it's best to keep VBS enabled.If you are a gamer or use resource-intensive applications, disabling VBS will minimize performance degradation.

How to Disable VBS in Windows 11 to Improve Performance

If you want to disable VBS, here are a few tricks you can try.

1. How to disable VBS from Windows settings

Follow these steps to disable VBS from the Settings app:

5. Now, check that the "Memory Integrity" switch is activated.If it is active, click it to disable the feature.

 

 

6. Reboot your system.Test some apps and games to check their performance.

2. How to Disable VBS with Command Prompt

You can also disable VBS using the command prompt.Remember that you must grant administrator privileges before executing the command.

3. How to turn off Windows virtualization

VBS can only run on your system when the virtualization feature is activated.If you turn off all Windows virtualization features, VBS will not work.Therefore, you have to uninstall some Windows features.

To turn off virtualization in Windows 11, follow these steps:

1. Press the Win key, type Control Panel and open the first result.

2. Find the Programs and Features option, and then click the Uninstall a program option.

3. Navigate to the upper left corner and click the Turn Windows features on or off option.

4. The Windows function will start.Find Microsoft Defender Application Guard, Virtual Machine Platform, and Windows Hypervisor Platform in the list.

 

5. Uncheck all these features and click the "OK" button.Wait for the settings to disable these features on your device.Click the "Restart Now" button to apply the changes.

6. Revisit Windows features and check if all virtualization features are not activated.

4. How to disable VBS from Local Group Policy Editor

You can use the Group Policy Editor to permanently turn off VBS.Keep in mind that GPE is not available to Windows 11 home users.You need to run a batch script to enable GPE.

To disable VBS using Group Policy Editor, follow these steps:

1. Press Win + R to launch the "Run" command box.Type gpedit.msc and press Enter to start the Group Policy Editor.

 

2. Navigate to Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard.

3. Under Device Protection, find the Enable Virtualization-Based Security policy and double-click it.

4. Click the Disabled radio button in the Policy window.Then, click the "Apply" button.

5. Click the "OK" button to exit the Group Policy Editor.Reboot your system to apply the changes.

6. To re-enable VBS, click the Enabled radio button in Turn on Virtualization-Based Security Policy.

5. How to Disable Virtualization via BIOS

The last option is to disable virtualization technology in the system BIOS.As mentioned before, if you disable virtualization, VBS won't work.So by doing this, you can be sure that VBS will never open.

To turn off Virtualization Technology from BIOS, follow these steps:

1. Restart your system.Enter the BIOS setup by pressing the corresponding F key (usually the F2 or F12 key).

2. Once you are in the BIOS, go to the Advanced Settings page.Remember, each OEM has a different BIOS appearance and settings layout.

4. Now, press F10 to save the changes.Exit the BIOS setup and continue the boot process of the operating system.

5. Check the Memory Integrity option in Windows Security.It will be grayed out.

VBS won't kill your system performance anymore

VBS is a pretty cool feature that is available in Windows 10 and 11.However, the drastic drop in performance certainly makes it less enticing to gamers.First, start by disabling the Memory Integrity feature in Windows Security.Then use the Group Policy Editor to turn off VBS.

After that, go to other steps to disable virtualization features like MDAG and Virtual Machine Platform.Finally, disable Virtualization Technology from the BIOS.Without it, features like VBS won't work.
