Hello, I have a windows 7 pro pc with kes installed. I removed kes using kavremover in safe mode since I could not find the password. After removal I have the peripherals not working, if i plug a vga a ps2 mouse and keyboard I can login. Checking with the Device Manager it says that network card, usb, cd devices are unusable with Error 19. Some corruption or block at a registry level. Is that some sort of security measure inside kes? Do you happen to know how can I fix that?
