This post shows students and new users steps to enable or disable Core Isolation Memory Integrity with Microsoft Security in Windows 11. Core Isolation is a security feature that protects critical Windows core processes from malicious software such as ransomware.
Core Isolation works with Memory Integrity (aka Hypervisor-Protected Code Integrity (HVCI)) in Windows to make it difficult for malicious software and scripts to use low-level drivers to hijack one’s computer. Windows Memory Integrity feature works by creating an isolated environment using hardware virtualization.
Without memory integrity running, the “security guard” stands right out in the open, where it’s much easier for an attacker to interfere with or sabotage the guard, making it easier for malicious code to sneak past and cause problems.
How to enable or disable core isolation memory integrity in Windows 11
As mentioned above, core Isolation is a security feature in Windows that protects essential core processes of Windows from malicious software such as ransomware.
In our analogy, this isolated environment (the locked booth) prevents the memory integrity feature from being tampered with by an attacker.
Turn on Core Isolation Memory Integrity in Windows 11:
In the search box on the taskbar, type Windows Security and select Windows Security in the results list.
In Windows Security, select Device security.
On the Device security page, click the link that reads Core isolation details.
Change the More integrity setting to On or Off.
If memory integrity fails to turn on, it may tell you you have an incompatible device driver installed. So first, check with the device manufacturer to see if they have an updated driver available.
That should do it!
