If a driver is incompatible with the version of Windows installed on your PC, it may interfere with how it works. That’s exactly the problem facing users who have come across the Brusbsib.sys incompatible driver error. Let’s dig deeper and find out possible solutions below.

Should I turn on core isolation in Windows 11?

Core isolation is a feature of the Windows 11 operating system that allows you to protect your computer from security threats by limiting what applications can do. It is good practice to turn it on as soon as possible to protect your computer from malware and other threats. For users who deal with virtual machines, turning on core isolation may be necessary. Enabling memory integrity in Windows 11 is a great idea to keep your PC safe from malware and other viruses. Memory integrity is another feature that prevents applications from accessing parts of the memory that they shouldn’t be able to access. However, you may find you can’t turn on memory integrity because of incompatible drivers. For users who experienced the Brusbsib.sys incompatible driver with the Brother printer error, they were unable to enable memory integrity on their PCs. The message said Brusbsib.sys incompatible driver preventing memory integrity from functioning. You may end up with an incompatible driver under the below circumstances:

Installing the wrong driver – A good example is if you have an Intel graphics driver and you install the AMD graphics driver instead. Your computer will probably not work correctly.  Installing a driver for a different OS – If you try to install a driver that has not been optimized for your version of Windows, you’ll have trouble getting your PC to work. Installing drivers from unauthorized sources – Some websites offer illegitimate drivers that may have been tampered with or altered, so they won’t work properly on your computer.
