I'll teach you how to learn. Registry System Appearance Modification Instance (5) _ Registry

The control Panel is an important part of Windows, it can directly modify the system's various properties, add and remove the software and hardware in the system, if your computer is shared, and you do not want others to use the function of which the contents of the computer to modify, you can screen some of the menu items of the method, at least for "Rookie", such a precaution is very effective.

The menu item masks in the control panel are mainly based on the Hkey_current_usersoftware microsoftwindowscurrent versionpolicies in the registry and its sub key branch, where we'll write this sub-key branch first (*) For the following reference.

Screened menu item in Control Panel	Right window add key Value entry position (new if no subkey)	Add Value type	Named as	Value is set to
Display Icon Item	(*) System sub-key branch	DWORD Double Byte	Nodispcpl	1

In addition, you can mask the File menu in Explorer to improve the security of your computer.

The method is as follows: Open (*) Explorer subkey branch, create a new DWORD Double-byte key value in the right window, name "Nofilemenu", and change its value to 1.

can also block out "My Computer" shown in the drive, such as shielding C and e disk, visible "My Computer" there is no such two letters.

　　
Method is to open (*) Explorer subkey branch, in the right window to create a new binary value, named NoDrives, its value can be set according to their preferences. The letter number corresponds to the binary number:

A disk corresponds to 1
b Disk corresponds to 2
C Disk corresponds to 4
D disk corresponds to 8
E disk corresponds to 16
F Disk corresponds to 32

And so on, add the disk symbol you want to mask, starting at a high level, and filling it with hexadecimal numbers on the data for that key value item. If C disk for the 4,e disk is 16, add 20, converted to 16 into 14, then fill 14 00 00 00 can, restart effective. At this time, from "My Computer", can not see the letter directly, but as long as the letter in the top of the address bar, the contents of which will be directly visited, hehe: As pictured, is not quite wonderful, do not know people really will be helpless.

　　
For a more thorough masking drive, we can disable MS-DOS because other people are still able to access the drive directly in DOS mode. Select (*) subkey branch, right-click New "Item", name "Winoldapp", create a new DWORD value in the right window, name "Disabled", set its value to 1, restart effective.

Alternatively, we can hide the contents of the folder, which is not simply to set the folder as a hidden file because someone else can see the hidden folder by selecting Show all file types. What we have to do is to make it impossible for someone else to open this folder or to know that it is a folder. If we need to protect the folder F:myfiles in MIDI file format for protection, find HKEY_CLASSES_ROOT in the MIDI file type of CLSID is {00022601-0000-0000-c000-000000000046}, Name the F:myfiles as F:myfiles. {00022601-0000-0000-c000-000000000046}, at which point the folder icon becomes the icon for the MIDI file, and double-clicking the file system uses MIDI to try to open it, which is clearly not open, and the contents of the folder are successfully protected. Here, I would also like to remind that a lot of virus programs that is the use of this method, will be some of the things that appear to be TXT file is actually a virus program, that is, a file named XXX. Txt. {xxxxxxxxx} Such a form, then the file appears to be txt extension, but in fact, with the corresponding program in the last sequence number opened. The simplest way to judge is to see if the icon for the file is the icon for the document file, and if not, that's the case. This way, you won't accidentally open the virus program again.
