Windows 11 Security - Core Isolation Memory Integrity

Thread needs solution

Windows 11 Home Version 21H1 OS build 22000.918

I cannot activate Core Isolation/Memory Integrity in this OS. The reason given is driver incompatibility with tib.sys.

I see this driver incompatibility issue was raised a year ago with no resolution provided at that time. When may we expect a response or solution to the problem? Thank you.

This problem also applies to Windows 10. The issue is not, as far as I am aware, going to be fixed in Acronis products that are out of technical support, that is ATI 2021 or older. There is a solution of sorts in the latest build of Acronis Cyber Protect Home Office, where the problem is avoided by not installing Try & Decide (the build allow selective installation of cyber protection modules as well).

There are work-arounds that can overcome the problem, which are describe is several forum threads.

This is a known issue and only resolved by Acronis in the latest build 40107 version of Acronis Cyber Protect Home Office which now offers a Custom Install option where users can now elect not to install the 'Try&Decide tool' feature (which brings the tib.sys driver to Windows).

For users of older versions of Acronis, see forum topic: Incompatible Driver(s): tib.sys? | Acronis Forum for information on how to circumvent the issue by renaming tib.sys to such as tib.~sys or by removing the associated registry entry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tib

Note: you may need to do a Safe mode start of Windows to action the above options.
