Win7 group policy hides system partitions

The partition where the operating system is located can easily be mishandled, especially in the case of a skin monkey like a poncho. 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 leather monkey will not mistake the system disk for trouble.
