I clicked, pushed or saved the absolute wrong credentials/drivers/etc using (I think this is the cause) of a program from Iobit called "driver updater". None of the roll-back options (program or Win10) can seem to fix it. I have googled the repair to a half-dozen sites, tried their suggestions with no positive results. Multiple inquiries from Iobit have not rendered a solution. I even went so far as to re=install windows, still nothing. I need a guru please.....
