Win7 system how prohibit the use of U disk?

In general, in order to back up files, we will use a USB flash drive to read and copy files from the computer. But in some special cases, in order to protect computer security important documents, we have need to disable the U disk copy computer data through a number of settings, then in Win7 system how to prohibit the use of U disk it? Below, we look together.

Method /

is achieved

by modifying the registry Open & rdquo; run & ldquo; box, enter the command & ldquo; Regedit & rdquo; into the registry interface.

2. Expand & ldquo; HKEY_LOCAL_MACHINE & rdquo; & rarr; & ldquo; SYSTEM & rdquo; & rarr; & ldquo; CurrentCntrolSet & rdquo; & rarr; & ldquo; Services & rdquo; & rarr; & ldquo; USBSTOR & rdquo ;, find key & ldquo in the right window; Start”, change its value from “3” to “4”, then restart the computer.

After the above setting, although the U disk is completely disabled, but due to inflexible, resulting in achieving the desired results. Let's take a look at the use of software to control the use of the USB interface. Another feature of this method is the freedom to control the USB interface.

1. Download & ldquo; the trend to the USB monitoring software & rdquo;, after the download is complete, run the installer directly to install.

2. When you use the software for the first time, the “USB password setting” window will pop up, where you can enter the management password.

3. In the main program window is open, make sure the & ldquo; USB interface control option & rdquo; below & ldquo; disabling only a USB storage device for & rdquo ;, & ldquo; prohibit all USB device & rdquo; option, it is recommended not to check, otherwise it will cause the USB mouse and keyboard are not available!

4. Of course, maybe sometimes our treatment will be more flexible, for example, only allow the computer to copy data from the U disk, you only need to & ldquo; USB storage devices to precisely control & rdquo; column , check the "Allow only copy data from U disk to computer" option.

5. Sometimes we will need an authorized user permissions to copy data using any U-disk, which should just check & ldquo; you can copy data from your computer to the U disk, but must Enter the administrator password & rdquo; option. Then re-plug the U disk to take effect.

6. When the setting needs to be specified, the last thing we need to do is to start monitoring capabilities of the software, click on the & ldquo; enable control & rdquo; button start Silently escorting us in the background.

7. In the meantime, even if someone tried to stop the monitoring function of the software, but I do not know, is to enter the normal password for the job, therefore, a good implementation of U disk Monitoring function.

The above is prohibited under Win7 system to use U disk, after the above steps, the computer will prohibit U disk copy files, so that we can take to protect data safe.
