The partition where the operating system is located, it is easy to be mistaken, especially the naughty child who likes to move the computer at home. So normally we can hide these system disks in the resource Manager from C disk and D disk. In Win7, follow these steps:
1, press the WIN+R key, input gpedit.msc, start Group Policy Editor;
2, in the Group Policy Editor in turn into the User Configuration →windows component →windows Explorer;
3, on the right to find "to prevent from ' My Computer ' access drive";
4, double click to open the dialog box, point "Enabled", from the following options to persuade only limit drive C, and then click Apply button.
So we can hide the C disk in the Explorer, not only in the resource manager not see the C disk, and even if the "C:" in "Run" can not access to the C disk, the child will not be mistaken for the system disk to make trouble.
