Let the Vista system only recognize the U disk that you specify

Now U disk has been very popular, you can buy 1G for dozens of dollars, and many mobile phone functions also have U disk function, so I want to copy some files from other people's computer, it is very simple thing This will pose a great threat to the data in the computer. In fact, there is no need to worry about this problem in the Vista system. We can disable all USB storage devices by setting, and also allow the system to use only the specified USB flash drive. Let us introduce the process of setting up.

Insert your U disk into the Vista system first, let the system use the U disk normally, then enter the "Control Panel", double-click the "Device Manager", expand the "Portable Device" inside, you can see Inside, there is your U disk, click the right mouse button to select "Properties", click the "Details" tab in the pop-up "Properties" window, and then select "Hardware ID" in the device "Properties" drop-down box, below A string will appear in the "value". This is the hardware ID of your USB flash drive. Copy it and save it.

We also need to copy the "USB Mass Storage Device" in the "Universal Serial Bus Controller". "Hardware ID, expand the "Universal Serial Bus Controller" list in the "Device Manager", find "USB Mass Storage Device", click on the "Details" tab in its "Properties" window, copy it out The hardware ID is also saved
