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.
