today I uninstalled Toshiba bluetooth stack because it was causing issues and restarted the PC. Then I have checked in System32 folder and the drivers corresponding to the Toshiba bluetooth stack were still there, so I have deleted them from System32 /Drivers folder and System32 /DriverStore / FileRepository. I have also deleted the related infinitives in Windows /inf folder.
Are there other folders in where I should check for leftovers of the drivers?

Thanks in advance, werty
