Hi
Welcome to Microsoft community.
To identify incompatible drivers that are preventing you from turning on Memory Integrity in Windows 11, you can follow these steps:
- Press the Windows key + X on your keyboard and select "Device Manager" from the menu that appears.
- In the Device Manager window, expand each category by clicking on the arrow next to it.
- Look for any devices with a yellow exclamation mark icon indicating a problem or incompatible driver.
- Right-click on the device with the exclamation mark and select "Update driver" to try updating the driver automatically. If that doesn't work, you can select "Properties" and then go to the "Driver" tab to manually update the driver or uninstall it.
- Repeat steps 3 and 4 for all categories in the Device Manager.
- Restart your computer after updating or uninstalling any incompatible drivers.
- Once you have resolved all incompatible drivers, try turning on Memory Integrity again by going to Settings > Windows Security > Device Security > Core isolation > Memory Integrity.
If you are unable to find any incompatible drivers using the Device Manager, you can also try using third-party driver update software to scan your system for outdated or incompatible drivers. These tools can often provide more comprehensive information about driver compatibility and help you update them accordingly.
Please feel free to let me know if you have any further updates. Thanks.
