Hi,
Try the solution provided by PCR:
Try a search in File Explorer for "Kr*.sys". That's an asterisk in the middle, & it will catch variations in the name. If found, R-Clk it for Properties, & look in the Details tab to see whether it identifies itself as
a Toshiba RAID driver. If so - no matter what folder it is in - rename it to something else.
