Please help. I am trying to copy my research files from a library computer into a USB Flash Drive but couldn't as the administrator disabled the USB port. I tried enable it back through Regedit. I went to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\UsbStor and type 4 and click Hexadecimal. I received an error message "Cannot edit Start: Error writing the value's new contents. I tried to get full permission for user to change it but was denied. Please someone help me. Thanks.
