Play Windows 7 unique features Control the automatic operation of USB devices

Although Microsoft's Windows 8 system has been released for some time, Windows XP still occupies more than half of the Microsoft operating system market. In our use of Windows XP, especially the use of USB devices by users, now usb devices Has become the first source of computer viruses, a little careless, your u disk may become a "drug disk", become a hotbed of computer viruses. Therefore, we usually let the usb device not automatically run after connecting to the computer. In winxp, you can modify the system configuration or the registry to achieve the effect that the u disk does not run automatically, but in the Windows 7 system, we have better The way the usb device does not run automatically.

If you have already used win7, you can control the automatic operation of the usb device through the system's own "privilege control" technology, how to do it? I will give you a detailed answer. So, how can we control from the source?

Everyone should know that when the USB device is plugged into the host computer, a later time, the system will prompt the XX device to be ready for use. This process is actually system identification, and The process of installing a driver for a USB device. We can take advantage of Windows 7's unique permission control feature, prohibiting it from automatically recognizing and installing the driver, so that it can achieve the purpose of controlling the source.

Go to the "X:\\Windows\\inf” directory (X: for the partition letter of Windows 7), find the “usbport.PNF” and “usbstor.inf” files respectively, and then separately The corresponding "Group or User" attribute security permission is set to <;Reject”. Take the setting "usbstor.inf" as an example:

Right-click on the "usbstor.inf" file and switch the "Security" tab in the pop-up dialog box to set the system default group or User “SYSTEM”<;Full Control" permission is set to “Reject”.

The SYSTEM default is fully controlled, and the user can enter the setup boot window via the "Advanced" button below. I will not go into details here.

Although this method can control the self-installation of USB devices from the source, correspondingly, when you plug the device into the host computer, the system will "mute", for your insertion behavior. Do not respond. Correspondingly, the author suggests that users should upgrade their permissions for their favorite users, so that they get the “full control” permission to achieve a flexible effect.
