I am trying to uninstall the utilities package for Brother MFC-7340 on my new laptop with Windows 11 OS. I want to be able to turn the windows core isolation security back on. I went to Brothers website and downloaded the uninstall program and used it. It apparently ran successfully but left behind one file (BrUsbSib.sys Windows\System 32\drivers). Took out the other three files that had loaded that I had identified. Ran the uninstall again, same thing. Rebooted laptop, same thing. So I still can't get the core isolation security tab to enable. Anybody else run into this problem? Any advice as to how to get rid of this last file? Thanks much for any thoughts/advice. RJH
