Hide the system partition with the win7 group policy

The partition where the operating system is located can easily be mishandled, especially for naughty children who like to drive the computer at home. So usually we can hide the system disk of C drive and D drive in the resource manager. In Win7, you can do the following:
1. Press Win+R, type gpedit.msc, and start Group Policy Editor.
2. In the Group Policy Editor, enter "User Configuration→ Windows Components & Rarr; Windows Explorer ";
3, found on the right “ Prevent access to the drive from "My Computer"  ;
4, double-click to open the dialog box, click "ld"; enabled & rdquo ;, from the options below, choose to limit the drive only C”, then click “ Apply button & rdquo;.
This way we can hide the C drive in the Explorer, not only the C drive is not visible in the Explorer, but even if you type "C:" in "Run" C drive, the little boy will not mistake the system disk for trouble.
