Hi guys, I am glad that you guys help a lot in this field. I really need one. In my office PC I want to disable usb flash drive function. but from regdit path(run to regedit hkey_locqal_machine_system_service), usbstor folder is not present. usbhub folder is there and is enabled so if I make it 4 (instead of 3) means disabled, will my USB keyboard and mouse or any other device working on USB stop working? I am little confused as not from field of IT or CS. PLease help me guys.
