BrusbSib.sys incompatible driver

Any clue how to remove BrusbSib.sys incompatible driver. So I can turn on memory integrity? There is no OEM number like the other 2 I deleted. There hasn’t been any brothers printers used in over a year and I have deleted everything in reference to the printer. I have looked everywhere to see if something is hidden and I can’t find anything. Much needed help appreciated! :(

    OK so from a previous post here that but the location of this file BrUsbSlb.sys, I tried removing it from the directory and I didn't have permission, so I gave myself full access to this file and removed it from the directory and placed it on my desktop (just in case) and then back to the Core Isolation, turned it on and rebooted all good, sorted!

    I tested my brother's 810w label printer and it still works.

    recap I removed this file BrUsbSlb.sys, enabled Core Isolation and rebooted job done

    dont understand your driver problem. if pc-fax was deactivated from the very beginning. there is no more core-protection deactivation problem. driver-remover by brother needed.thats normally not he case since nobody knows about the problem. dont change anything in the registry. i thought i explained clearly. if not go to sysopt where i explained it in details. brothers old software( i mean when they started selling this model) or maybe same on others) has a issue in pc-fax-function. it must be deactivated. its old printer. they will not invest anymore. wishful thinking. workaround came from brother after i had found out how to remove. to cure repeating the problem. look here for detailed instructions if not given here.me: europanorama

    nice work Pankaj
    Followed similar process but simply did the pnputil /delete-driver <with offending driver listed by memory integrity> and bang all fixed once restarted..
    one has to wonder why brother didn't simply let out a drive uninstall too that actually worked,.,

    I tried all the above, to summarize:

    1. Downloaded and Installed Brother software in full (i have an MFC-9340-CDW). Then uninstalled it. Restart, No difference.
    2. Downloaded and install the Brother Device uninstaller. It expands to c:\downloads. Navigate to the directory and run it. It runs, doesn't show anything useful, completes. Restart, No difference.
    3. Widows App uninstall programs. Remove anything if any related to Brother. Restart, No difference.
    4. Went to Device Manager: removed the 'Brother Fax ...' from Print Queues. Restart, No difference.
    5. In Device Manager, sort by devices by driver. There is no BrUsbSib.sys to be found.
    6. Lastly, search for BrUsbSib.sys on the C: drive. Found in c:\windows\system32. Deleted manually. Restart, Worked!

    I suspect that the Brother ultilities/device installer is too dumb to find the exact location and/or looking for a different file name. It probably did remove device drivers, but not that one. Feels like a bug to me.

    Also, I do not recommend deleting various other drivers through device manager (oemXX.inf) unless you absolutely know its related to brother.

    I went to c:\windows\system32 and did a search for BrUsbSib.sys and got no match. Is it in a folder within c:\windows\system32 ?
