How to Fix Memory Integrity Blocked by Incompatible Drivers in Windows
Question details
The user is unable to enable Memory Integrity in Windows Security because incompatible drivers are blocking the feature.
- Product
- Windows
- Device & OS
- Windows
- Scenario
- Trying to enable Core Isolation Memory Integrity in Windows Security settings to improve system protection.
- Observed behavior
- Memory Integrity fails to turn on, displaying a warning about incompatible drivers, and the automatic resolve option does not fix the issue directly.
Before making changes to system drivers, ensure you are logged into an administrator account and have created a Windows System Restore point in case you need to revert changes.
Identify and Resolve Incompatible Drivers via Windows Security
Use the built-in Windows Security details to locate the specific drivers causing the block and manually update or remove them.
Windows Core Isolation requires all system drivers to be fully compatible with its security standards. If legacy or third-party drivers conflict, you must manually update them to compatible versions or completely remove them from your device.
Go to Start > Settings > Windows Update and click 'Check for updates'. Install all available updates, as Microsoft frequently bundles compatible driver patches in standard system updates.
Open the Windows Security app, click on 'Device security' in the left pane, click on 'Core isolation details', and look for the Memory Integrity toggle.
Click the 'Review incompatible drivers' or 'Resolve incompatible drivers' link below the toggle to view the exact list of problematic driver files (e.g., specific .sys files).
Note the publisher and file name. Visit the device manufacturer's official website or the Microsoft Update Catalog to download and install the latest, compatible version of each listed driver.
If the incompatible driver belongs to software or hardware you no longer use, open Device Manager, locate the device, right-click it, and select 'Uninstall device'. Check the box to 'Attempt to remove the driver for this device'.
Once all problematic drivers have been updated or removed, restart your computer. Open Windows Security again and toggle Memory Integrity to 'On'.

Frequently Asked Questions
What is Memory Integrity in Windows Core Isolation?
Memory Integrity, also known as Hypervisor-protected Code Integrity (HVCI), is a Windows security feature that prevents malicious programs from inserting harmful code into high-security system processes.
How do I find the specific name of the incompatible driver?
In Windows Security, navigate to Device security > Core isolation > Core isolation details. Click 'Review incompatible drivers' to see a list of specific driver file names (usually ending in .sys) that are causing the conflict.
Is it safe to leave Memory Integrity turned off?
Your computer will function normally with Memory Integrity disabled. However, leaving it off reduces your device's overall protection against advanced malware, so it is highly recommended to resolve the driver issue and enable it.
How can I delete a driver using Command Prompt?
Open Command Prompt as an Administrator and type 'pnputil /delete-driver [PublishedName.inf] /uninstall /force'. Replace the bracketed text with the specific INF name of the incompatible driver shown in your Core Isolation details.
