Windows 10: I need to delete a file that prevents Core isolation - BrUsbSib.sys - Memory integrity...

I'm running Windows 11.I'm trying to delete the file BrUsbSib.sys, as it prevents me from protecting memory integrity and the computer is vulnerable to malicious software attacks. I located the file in one of the System folders see screenshot below. When I try to delete it, I get a message that SYSTEM permission is required. I believe this file has nothing to do with my Brother printer, as many other people on the web have had the same problem for a long time and there are quite a few discussions about this file and how to eliminate it. What is the easiest recommended manner to overcome the

core isolation not supported

The igdkmd64.sys is the Intel HD graphics driver for your 1st gen i3 M380. I have the same with my i5 M520.






This processor generation is long out of support and Intel have stopped developing the drivers for them. There are no new drivers compatible with Memory Integrity.

The only way to turn on Core Isolation would be to uninstall the Intel graphics drivers and use the Microsoft Basic Display Adapter instead. That's not really a practical solution so you (and I) must accept that we cannot use Core Isolation. This is not as bad as it sounds, the benefit of Memory Integrity is that it prevents malware sneaking in as a driver update. But it shouldn't be able to get that far if your AV protection is doing its job. More here from the How-To Geek:

Deleteing stuff just to fix Core Isolation Memory Integrity

Hello, BlackViper0007

Welcome to Microsoft Community.

I understand your frustration. Core Isolation Memory Integrity is a security feature of Core isolation that prevents attacks from inserting malicious code into high-security processes. If you are experiencing the "Core Isolation Memory Integrity" error message, it's possible that it could be caused by a compatibility issue between your software and this security feature. One way to determine if this is the case is to try disabling "Core Isolation Memory Integrity" and see if the error message disappears. If the error message disappears after disabling this feature, it's possible that your software is not compatible with this security feature.

Another way to determine if there is a compatibility issue is to check if there are any known issues or conflicts between your software and "Core Isolation Memory Integrity" by contacting the software vendor or checking their website for any compatibility information.

it would be a good idea to contact the software vendor to see if they have any solutions or workarounds for this issue. They may have updates or patches available to address the compatibility issue. It's also possible that they are aware of the issue and are working on a solution. Contacting the vendor is a good first step to take in resolving this issue.

Let us know if you have any further questions.
