Usually, the problem happens because an old Brother USB driver is still on the computer, even after you removed the device or updated the software. Often, the file is linked to a setup file like oem41.inf. You may need to find and delete this file by hand. This guide will walk you through several steps to fix this issue and successfully turn on Memory Integrity.
1. Check for Updates for the Brother Software Driver
Outdated drivers often cause compatibility issues that prevent Memory Integrity from working. It’s a good idea to check for newer versions, as Brother regularly updates their drivers for better performance and security. You can look for driver updates through Device Manager or download them directly from the official Brother website.
2. Turn on Virtualization-Based Security in Local Group Policy
Windows uses Virtualization-Based Security, which sets up a secure area using hardware virtualization to help protect your system from potential threats. Although turning this on doesn’t directly enable Memory Integrity, it helps set up the right environment for it and other security features. You can turn this on through the Group Policy Editor. Note: If you’re using Windows 10 Home, the Group Policy Editor isn’t available by default, but you can enable it using this guide.
3. Force Uninstall BrUsbSib.sys Using Command Prompt
If updating the driver doesn’t help, you can remove the BrUsbSib.sys driver using the Command Prompt.
4. Use AutoRuns to Prevent the Driver from Starting Up
If the problem is still there, you can try using AutoRuns, a free Microsoft tool that shows you everything that starts up with Windows and lets you stop or remove unwanted drivers like ‘BrUsbSib.sys’.
5. Uninstall Brother Software
If nothing else works, you may need to uninstall the Brother software completely. This step should only be done if you’re not able to fix the problem with the previous methods. Using the official uninstaller from Brother makes sure all related files are removed and allows Memory Integrity to work.
