Hi. I'm David, and I'm happy to help you.
Yes, try turning it on first.
Attempting to switch Memory Integrity to On triggers a compatibility check. If everything is fine, it will simply turn on. If a driver is incompatible, the switch will fail and display a "Review incompatible drivers" link.
Here is the easiest way to proceed:
- Go to Windows Security > Device security > Core isolation details, then switch Memory Integrity to On.
- Then, check the result:
- If it turns on without error, restart the computer to finish.
- If it fails or turns back Off, click the "Review incompatible drivers" link.
- If a list of drivers appears, take a screenshot of that screen and post it here in a reply. Use the shortcut "Windows + Shift + S" to use the screenshot tool. Seeing the exact driver names will make it much easier to provide step-by-step guidance on how to fix or remove them.
Feel free to ask any questions you may have.
