    Windows 11 core isolation memory integrity won't turn on


    I upgraded to Windows 11 from 10 two days ago. All was fine until now when Windows security tells me it cannot turn on Core Isolation memory integrity. When I clicked on "Review incompatible drivers" it listed several for Trusteer Rapport. So I uninstalled it. After rebooting, powering down and restarting etc., the problem persists, except when I run "Review incompatible drivers" the list is empty. Windows appears to find nothing that is incompatible.Please note I would be uncomfortable doing such things as editing the registry.What can I do to fix this?

    Problem with memory integrity and isolation cores

    Hi Kaelyn. I'm Greg, here to help you with this.

    There are a number of cases with Core Isolation Memory Integrity error recently. Here is what is resolving most cases:

    Windows 11 core isolation memory integrity won't turn on

    Core Isolation- Memory Integrity

    What is Memory Integrity in Core Isolation? Is it helpful to avoid malware, phishing, and ransomware? Is there any Performance drop when Memory Integrity is turned on? What is the percentage of performance drop? Does it affect battery life when memory integrity is turned on? Does it also increases CPU usage?

    Please answer all my questions and give another information about Core Isolation- Memory Integrity regarding Battery life, CPU usage, RAM usage, and System stability,
