core isolation disabled itself in bios on new computer

Hello Khynnea,



Thank you for writing to Microsoft Community Forums.



It can be the BIOS update released by your manufacturer through windows updates which might have changed the status from Enabled to disabled. However here are the steps to enable it again.

• Open start menu and search for Windows Defender Security Center.
  
• Go to Device Security.
  
• You will be able to find Core Isolation, please click on Core Isolation details.
  
• Then you can turn it on.
  

Restart is restart is required for the changes to be effective. Please write back, if you need any further assistance.

Hope it helps.

Turn On or Off Core Isolation Memory Integrity in Windows 10  


It looks like the .reg file in step 2 of Option Two in this tutorial worked to turn on Core isolation for you.

Correct, you could use step 3 to turn it off.

 

Core Isolation preventing a driver from loading

The driver "gdvr3.sys" was causing core isolation to turn off. After turning it back on and restarting, get the message that Core Isolation has blocked the driver from loading. However, it is not showing up under problems when I look under core isolation details. Not sure what next steps need to be.
