How to completely shield U disk in Windows 7 system

In the article "Disabling Windows 7 to automatically recognize and install drivers for USB devices", we have actually "closed" to solve the problem of "USB devices automatically run poisoning". But there are users who like to go to extremes: require direct shielding of USB devices.

In this article, you can learn about the following:

Windows 7 can effectively control USB devices, but each time you want to increase the permissions for a user.

Modify the registry to completely shield the USB device (re-enable it when needed).

It can be seen from Windows 7 that the control of USB devices is comprehensive.

In Windows 7, run the Registry Editor, expand to HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\services\\USBSTOR, find it in the right window and double-click "Start", then in the pop-up window, Its default value is changed to "4".

After the modification is completed, save the settings and exit, and it will take effect after the next restart.

After using this method, the USB device in Windows 7 will be disabled. If the user needs to enable the USB device, you must enter the above key value again and change the value back to "3".

Edit Comment:

Compared to the method of controlling Windows 7 permissions, the method described in this article is very "perfect", but you need to modify the registry every time. This is a very troublesome thing. Therefore, I do not recommend using this method.
