Hello I am trying to figure out the most efficient way to disable usb storage for all non-admin users, but have the "admin" account have access in windows 7, I am creating a image for deployment. I have read a plethora of forums trying to solve this riddle and I haven't yet found my answer. I have tried the dword USBSTOR change from 3 to 4 by creating two batch files(disable and enable), but there seems to be an issue with that. Do I have to restart the machine each time I change the key? I noticed that switching from 4 to 3 resulted in the usb drive not installing the driver. Thank you for any and all advice.
