Disable Virtualization-Based Security (VBS) in Windows 11 (2021)

Before getting to the steps to disable Virtualization-Based Security, we have added a brief explainer on the feature and the steps to check your Windows 11 PC’s VBS status. We have also created a pros/ cons list on what to expect if you disable VBS, which will hopefully help you make an informed decision. With that said, let’s get right into it.

What is Virtualization-Based Security (VBS) in Windows 11?

Virtualization-Based Security (VBS) is a security feature in Windows 11 (and Windows 10) that creates an isolated region of memory for security features. This virtual secure mode is created using Windows hypervisor and is separate from the rest of the operating system. Microsoft says VBS can reduce the impact of kernel viruses and malware attacks. One key security feature enabled through VBS is memory integrity or Hypervisor-protected code integrity (HVCI). It checks all kernel-mode drivers and binaries before they are started and stops unsigned drivers or system files.
Notably, VBS isn’t a new Windows 11 feature and has been around for years on Windows 10. What’s new, however, is the enforcement of the feature. While VBS was optional in Windows 10, Microsoft started enabling VBS by default for some PCs in late 2019. Moreover, the Redmond giant is encouraging OEMs to enable VBS by default on PCs shipping with Windows 11 out of the box. Although VBS might be disabled if you manually upgraded from Windows 10 to Windows 11, it’s likely enabled if you purchased a new Windows 11 laptop or pre-built PC. You can check the next section to know your PC’s VBS status.
Now, you might be wondering why you should disable VBS in your Windows 11 machine, especially since it is a useful security feature. That’s where things get tricky. According to benchmark tests done by popular GPU stress test software 3DMark’s maker and independent tests done by PC Gamer and Tom’s Hardware, enabling VBS impacts performance, especially when you are using your Windows PC for gaming. So if you are facing FPS drops in games on your Windows 11 machine, you could consider disabling VBS to increase the gaming performance.

  1. In Registry Editor, navigate to the path given below and double-click on ‘EnableVirtualizationBasedSecurity’ on the right pane.
  2. Set the value data of EnableVirtualizationBasedSecurity to ‘0’ and restart your Windows 11 PC.

Method 4: Disable Virtualization-Based Security (VBS) from Group Policy Editor

Note: This method won’t work on Windows Home editions even if you have used the workaround to enable Group Policy Editor.

  1. Open the Run window using the Windows 11 keyboard shortcut ‘Win + R’, type ‘gpedit.msc’, and click on OK.
