I have tried safe mode, yes. I guess I will try and get hold of a PS2 keyboard and see f I can get it in that way. Otherwise I am locked out and cant clean registry or do anything else :/
But let's say I do get into the system, what can I do to get usb working again, except for malmware check? As I mentioned before, I just recovered it from crash, so many stuff are not working or missing dlls, such as installer, msservice, list goes on. How can I repair them?
