I can't turn on the memory integrity ( core isolation ) because of zntport.sys incompatible drivers. How can I solve it??
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
After hours of trying various "solutions" that did not work, I navigated to the location of zntport.sys and changed its name to zntport.sys-old. Next I went into Core Isolation and turned on the service. Then restarted the computer. Result: everything worked. The service in Core Isolation remained On; the renamed driver was present and no new copy of the original file was present.

Glad to help!
Hi, I am Dave, I will help you with this.
1
Please provide a screenshot of the listing of that incompatible drive in the Memory Integrity settings, there is usually more information in there that can help to solve the problem, like the OEM name of the driver.
2
Do you have software named NTPort Library by Zeal SoftStudio installed on your PC?
I uploaded a screenshot and no I do not have software referring to NTPort but there is a driver I guess
