In order to strength the system security, the VBS is enabled by default on Windows 11. The VBS is the short name of Virtualization-based Security which is used to isolate secure memory and host security features by using hardware virtualization. The Windows 11 VBS function plays an important role in the Windows 11 security protocols. However, some users find that the enabled VBS will degrade the gaming performance, so they try to disable VBS in Windows 11. This article will tell you what is Windows 11 VBS, how to disable Windows 11 VBS and should you disable Windows 11 VBS or not.
What is Windows 11 VBS?
The Windows 11 VBS security function uses hardware virtualization to create a safe memory area to run programs, thereby isolating the program from the operating system. Disabling VBS can greatly strengthen the system protection to prevent malicious attacks. After enabling VBS function, even if a software or hacker are not allowed to read the contents of this separate VM even they have administrator-level permissions. It makes your Windows 11 more secure. This is completely consistent with the working principle of today’s cloud.
However, for game users, enabling Windows 11 VBS will obviously impact the game performance. For certain AMD processors, the performance will be degraded 28% after enabling VBS. For most hardware, the average impact of VBS on performance is about 5%, so you can disable VBS if you want to improve the performance of Windows 11 fully.
Note: Disabling Windows 11 VBS function will cause applications that rely on virtualization technology, such as Hyper-V, VMWare, etc., to fail to run normally.
How to Check If Windows 11 VBS Is Enabled?
Generally speaking, if you are upgrading from Windows 10 to Windows 11, then VBS is disabled by default, and there is no need to disable Windows 11 VBS. If you reinstall the Windows 11 or buying a new computer with Windows 11, you need to check whether the Windows 11 VBS VBS is disabled on your computer.
So how to check it?
Open the search bar, enter info, and then click the system information application.
Open the system information page, there is a “Virtualization-based security” at the bottom, and the current status of VBS will be displayed here.
If VBS is “Not Enabled”, then there is no need to do anything. If it is “running”, then disabled VBS by the following steps.
How to Disable Windows 11 VBS to Improve Gaming Performance?
There are two methods to disable Windows 11 VBS:
Method 1 Disable Windows 11 VBS via Settings
Open the Settings panel in the start menu>Privacy & Security>Windows Security>Device Security >Clicking the Core Isolation Details link>click the toggle switch to the Off position. And then restart your computer.
Method 2 Disable Windows 11 VBS via Registry
Press Windows plus R keys, type regedit and hit enter.
Locate to HKEY_LOCAL_MACHINE/System\CurrentControlSet\Control\DeviceGuard, and set the DWORD value as 0 for EnableVirtualizationBasedSecurity. And then restart your computer.
For computer gamers, the gaming performance is indeed degraded greatly compared with Windows 10. if you pursue better and faster gaming performance, disabling Windows 11 VBS would make sense, even though there are risks involved.
On the other hand, VBS and HVCI can prevent hackers to run malicious code and trusted applications and drivers on your system because these malicious programs cannot go through the code integrity check. These features are precautionary measure developed to in response to recent ransomware attacks. So, it’s hard to say you should and shouldn’t disable Windows 11 VBS.
