<\/p>\nWindows 11 Core isolation is a section of Windows Security that contains the Memory integrity feature (also known as HVCI): a protection mechanism that verifies kernel code in an isolated environment. Starting in October 2026, Microsoft began enabling it automatically on more compatible PCs through regular Windows updates. Below is what this means, who it affects, how to check the feature\u2019s status, and how to disable it if it causes problems.<\/p>\n
Memory integrity is a Windows feature that uses virtualization (VBS) and the system hypervisor to run kernel code integrity checks in an isolated environment. Put simply, it helps prevent malicious or untrusted code, including drivers, from running at the deepest level of Windows.<\/p>\n
In Windows Security, it is located in the \u201cCore isolation\u201d section. It is also called Hypervisor-protected Code Integrity \u2014 HVCI.<\/p>\n
<\/p>\n
According to Microsoft, starting in October 2026, regular Windows quality updates will begin enabling memory integrity on a larger number of eligible devices. If virtualization-based security (VBS) is not enabled, updates will also turn it on where required. Before doing so, Windows checks each device to determine whether the hardware supports it, whether drivers and applications are compatible, and whether performance would be affected.<\/p>\n
The feature is already enabled by default on clean Windows 11 installations that meet the requirements and on Secured-core PCs. However, on devices upgraded from older versions, the existing default policy was not applied \u2014 and these are the devices the new rollout will primarily cover.<\/p>\n
Important: PCs where memory integrity has already been disabled manually will not be automatically changed by this rollout.<\/p>\n
Materials describing the change list the following PC requirements:<\/p>\n
If your computer does not meet the requirements or Windows detects driver problems, the feature will not be enabled automatically.<\/p>\n

System Information<\/strong> Press Win+R, enter If the feature will not turn on, the most common reason is an incompatible driver. In the \u201cCore isolation details\u201d window, Windows usually displays a list of drivers blocking activation. Update them to the latest versions from the device manufacturer. Microsoft has also documented issues ranging from failures in certain applications to incompatibility with some anti-cheat systems in games. If a driver is old and no update is available, it generally needs to be removed or replaced rather than forcing the system to work with it.<\/p>\n Yes, it can, but not always. Back in 2022, Microsoft acknowledged that Memory integrity could reduce gaming performance on some configurations and advised users who prioritize performance to temporarily disable it while gaming, while warning that doing so reduces security.<\/p>\n The impact depends on the hardware: newer processors with hardware acceleration for isolation handle it better, while older ones that rely more on software emulation may lose more performance. The announcement sources do not provide specific numbers, so do not trust \u201cuniversal\u201d FPS tables \u2014 test it on your own PC.<\/p>\n If enabling it causes problems with a specific game, application or driver, Windows 11 Core isolation can be disabled. A separate case is AMD overclocking: according to user reports, Ryzen Master may refuse to work while virtualization-based security (VBS) is enabled. Before disabling the protection, consider whether you really need that program.<\/p>\n Through the interface:<\/strong> \u201cWindows Security\u201d \u2192 \u201cDevice security\u201d \u2192 \u201cCore isolation details\u201d \u2192 \u201cMemory integrity\u201d switch \u2192 \u201cOff\u201d \u2192 restart.<\/p>\n Through the registry (run as administrator, with a backup):<\/strong><\/p>\n The Verification after the change:<\/strong> repeat the PowerShell command from Method 2 \u2014 the value Should you disable it? Generally, no: this is one of the important kernel protection layers.
