Hiding hard drives in windows system

hello all,
In this article I am going to tell you how can you hide your hard drives in windows system.
In order to do that what you have to do is:
go start->run->gpedit.msc
A window of 'group policy' will be opened. At the left hand side go to the
local computer policy->User configuration ->Administrative Templates->windows components
->windows explorer.
It will open a list of options in the middle of the "group policy" window.
Double click on the "hide these specified drives in my computer" option.
A new window will be opened.
From "setting" tab check the "Enabled" option.
And from the "pick one of the following options" select the drives that you want to hide.
click apply/ok to get out of the window.

Done.
now your desired drives that you wish to hide will be hidden.
