Hi, Running a business edition of Vista, I need to remove a Vid_Pid in the Usb folder in order to re-enumerate a device but somehow it does not let me, invariably returning an error message "error deleting Vidxxxx". I am doing this from an admin account and UAC has already prompted me to elevate my rights. I also have tried running Regedit from an elevated prompt but it made no difference. I have tried deleting other Vids to no avail. Thank you for your time.
