Hello, I have left HP printers and scanners drivers. I have changed some service settings ('Tweaked Black Viper's'). I have checked every compatibility mode excluding IIS and System Recovery. I have deleted everything green from 'this guide'. I'm installing HP software without any errors, printer is working but OS doesn't see any scanner. When I try to manually add a scaner, I have listed only one Xerox device (!?). If I search in HP installation files, OS doesn't find any drivers. Please forgive me my English and help me with my problem
