Problem Windows 7 can effectively control USB devices, but each time you need to upgrade permissions for a user. This article looks at the registry and completely shields the USB device (re-enable it when needed). Knowledge points can be seen from the comprehensiveness of Windows 7 control of USB devices.
In Windows 7, run the Registry Editor, expand to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesUSBSTOR, find and double-click "Start" in the right window, and then in the pop-up window, change its default value to "4".

Change the Start value to 4

Editor's Comments:
Compared to the way to improve the control permissions of Windows 7, the effect of the method described in this article is very "completely", but each time you need to modify the registry, this is a very troublesome thing. Therefore, I do not recommend using this method.
