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 B aware to use custom-installation and uncheck PC-FAX (here is the reason for the problem , outdated driver brother told)or if one can still see the brother iprint-scan entry under brother at left side clicki there to reactivate the driver(instead of full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.
