It is strange that after I disabled usb in registry key (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor, then in the right pane, find "Start" key, view it's value, (4=Disable USB Drives), I can still plug in usb jump drive to the computer and be able to read the stuff in the drive right after I reboot the computer. But after I unplugged the drive and plugged it back in, it won't work as expected. I wonder why it works first time after the computer reboots.
Any thoughts on this?
Thank you very much!
