Brother printer-driver BrUsbSib.sys(oem94.inf) blocking Core Protection-win10s.

Have big problems with Brother-Printer-Software(for MFC-L2710DW multifunctional Laserprinter) blocking activating Core Protection(german: Kernisolierung). see attached image.
there are workarounds. pnputil /delete-driver (name of driver) didnt work. since oem94.inf is used by multiple instances. windows 10 stopped it.
best was using deinstaller by brother. it will not remove software at all. only registry-remains.
But then had problems with no more Duplex-printing.
Lately installed software the right way. But in device-manager i saw exclamation mark.
No i am unsure what next.
I am also unsure if core protection was activated when in installed.
could check my other ultrabook for the same problem again. there it happended for the first time.

deleted driver in device-manager but only deleting with brother deinstaller unblocked core protection-activation.
as a result duplex-printing is greyed out inb pdf xchange viewer. alternative pdf program(dont remember maybe pdf viewer plus) seems integrated in SW. which i removed also using deinstallation in brother utilities
I can print but not scanning without Bro-SW. Brother must take care of this problem. win10s and 10 are declaring the driverfile BrUsbSib.sys(oem94.inf) as dangerous.Attachment 10076

Brother seems to have solved the Core Protection-problem but Duplex-printing outside Brother-Printing-app/driver remains blocked.
Tried multipe pdf- programs now. no duplex. in last one one can activate(a bit hidden) but no result.
Pdf xchange viewer, lite version and editor. last one installed(have 1 year trial) Soda pdf.
Nothing can be changed in windows 10 itself-10s to be precise here.

Core Protection blocking solved-Not Duplex outside Brother-SW

News about driver-compatibility. I am surprised.
coming from here:
https://support.microsoft.com/de-de/...9-de7ca31d2b37
https://support.brother.com/g/s/id/o...10s.html#mfc-j
MFC-L2710DW is listed and compatible
Only Utilities nonworking. Had them once installed. not anymore.
Brother original drivers on the CD-ROM/DVD-ROM bundled with your Brother machine or available in the download page are NOT compatible with Windows 10 S.
-------------------------------

Utility softwares (ControlCenter/ PC-FAX software/ BRAdmin Light/ PaperPort™/ Presto! PageManager .etc) are NOT compatible with Windows 10 S.

Any models not listed below DO NOT support Windows 10 S.
------------------------
in my case duplex only possible within brother-software. can live with it. latest installation was auto-update. so not complete package installed. yes i dont see utilities anymore with deinstaller integrated.
will check the same on win 10 machine and reinstall driver.

The same problem also with win10 ultrabook i7. core protection blocked.
after a longer time of unused ultrabook-win 10s-ultrabook was used-i had printing problems. only after windows updates i could print. then i recognized the same duplex-printing blocking outside brother-printer -sw.
Then i remembered uninstall-SW by Brother. in reality its only removing registry-entries brother-expert told.
After that i could reactivate core protection(in german: Kernisolation). its now asking to restart. see you.

Hope its solved by this:
PS C:\WINDOWS\system32> pnputil /delete-driver oem94.inf /uninstall /force /reboot
Microsoft-PnP-Hilfsprogramm

Das Treiberpaket wurde deinstalliert.
Das Treiberpaket wurde erfolgreich gelöscht.

Core-isolation/protection could be activated. only have to restart. i wonder what will happen when brother-printer-SW had been reinstallated. and if i need to remove oem94.inf again without removing SW.
had the same with rappoo-mouse-driver. not with hama-mouse.

SOLVED -old driver not adviced to use. Thanks Brother for solution

Go german tip what was wrong from Brother Germany.
Old driver/program-package not advised to use.

I can scan but tried only from device.
Must discuss with brother if there will be options nonworking anymore then.
Will check and show correct driver.

SOLVED

SOLVED-Core Protection in Windows 10 not deactivated anymore when deactivating "Remote Setup"and "Receiving Fax" during installation of Complete Driver/Software-package. First one ontop of list.
----------------------------------------------------------------------------------------------------------------------------------------------
The official solution by Brother-in German first:
"BRUsbSib.sys" kommt nur noch in zwei älteren, nur selten verwendeten Zusatzfunktionen vor. Es handelt sich die Tools ‚Remote Setup‘ und ‚Fax Empfang‘.

Diese Funktionen werden nur bei der Verwendung des Kpl. Treiber & Software Pakets installiert. Bitte verwenden Sie die benutzer-definierte Installation und deaktivieren Sie diese Funktionen in den Optionen. Auf diese Weise können Sei auch das Kpl. Treiber & Software Paket zur Installation verwenden.

Fazit: die Tools ‚Remote Setup‘ und ‚Fax Empfang‘ in der benutzer-definierten Installation deaktivieren.
That file BrSib.Sys (which is blocking Core Isolation maybe named Protection) exists only in these two seldom used functions in complete(large) Software-package around 400mb ontop of download-list.
by using custom-setting during installation and deactivating "Remote Setup" and "Receiving Fax" Core Isolation/Protection in Windows 10 will not be deactivated anymore. Remote-Setup is setting up printer within software. rightclick when seeing to get information. Bad thing is there is no Alarm when deactivated one must check.
I finally asked Brother Germany how Receiving Fax could work again.Attachment 10079
When you see that problem somewhere pls add a link to this solution.

All the time one is reinstalling driver other OEMx.inf is related to incriminated BrUsbSyb.sys file.
Core Protection had been deactivating again now. oem8.inf the file to be removed. hope this would work without removing Software.Attachment 10080

SOLVED NOW REALLY-one must go and get new oemx.inf file to remove it.

SOLVED NOW. After installation the right way coreprotection will be deactivated again. by removing the related oemx.inf file with the mentioned command, coreprotection can be activated again.
I can use software and scan from there.

not getting but checking core protection(will be deactivated) for related oemx.inf version to delete with command.
1. doing what i advised during SW-installation. then going to coreprotection(deactivated again) to get new oemx-inf-file related to incriminated BrUsbSyb.sys file.
removal command:
pnputil /delete-driver oemx.inf /uninstall /force /reboot
x=number

Core Protection went off/deactivated without warning. Reactivating and restarting helped.
Microsoft should implement warning! Maybe its for security reason they will not do.
Brother didnt know newest oemx.inf must be removed deleted afterwards.
filename will be changed over the time so our title-correction-new filename-wasnt necessary. All in all i like Windows 10 best. One can live now peacefully.
windows 10 home here on Acer Swift 5. i7. 16/1tb. white ultrabook old not very solid construction. better getting semirugged version. only acer really know the truth. keyboard and screen nonsolid. and their is a shocksensor which could stop these items from working. I added now antislip rubber surface.

After a reset of windows 10 problem came again after i reinstalled the full package-pcfax was disabled.
could mean i should have run deinstaller first.

Final Solution to avoid Core Protection staying disabled

Could enable core-protection til the moment after i had to reset Windows 10 home 64 since after Windows-Update constantly sound was gone. nothing could cure that.
yes one had to replace sound-room.or similar maybe that was not done and MS found a solution at least to show how to do. its taking some time sometimes til all the settings are correctly done.

Brother removal tool wasnt used before reinstallation of the app. B aware to use custom-installation and uncheck PC-FAX (here is the reason for the problem , outdated driver brother told)or if one can still see the brother iprint-scan entry under brother at left side clicki there to reactivate the driver(instead of full custom-installation. what will happen when using utilities i dont know.
i only know after deinstallation i still could use parts of brother printing tools to print.
autoruns
it was told that autoruns will find the BrUsbSib.sys but this wasnt the case only deleting the oem-inf helped. maybe reset deleted BrUsbSib.sys but not oem.inf
here is the forced command:
C:\WINDOWS\system32> pnputil /delete-driver oem94.inf /uninstall /force /reboot
when trying to enable Core Protection and if it fails BrUsbSib.sys will be show, by clicking the rightside arrow more will be shown. its the oemx.inf file or files shown. they must be removed.
