What is the Vista system group policy, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

If you regard the use of the operating system as practicing martial arts, then there are "secret books of martial arts" to refer to in the process of learning some martial arts. With the help of the "secret book", you can turn on the hidden functions of the windows system, and better protect personal privacy and system security.

I own my flash drive.

Everyone's computer will have some secret information or data that needs to be protected. If others have the opportunity to connect to their own computer, they can easily copy the data through USB mobile storage devices. To prevent them, if all USB devices are banned, it will not be convenient for them to use them. In fact, as long as the system only recognizes its own flash drive, the problem can be solved. This can be achieved without the need for other software to use the Group Policy Editor in Vista.

First of all, connect the USB disk that needs to be "certified" to the computer, and the next operation is to ensure that the USB disk can be correctly identified by the computer. Go to the desktop, right-click on "my computer" and select "Properties", and then click "Settings Manager" to view the connection of all the hardware in the current system. Continue to click "Portable device", use the right mouse button to select the device in the list and view the properties. Under details, select hardware ID from the properties menu and view it.

Next, Nanjing University will click to enter the "Universal Serial bus Controller", select "USB mass storage device" to view the properties, and also record the hardware ID. If all of the above operations can be viewed in the hardware ID, then you can continue with the next operation. After entering the Group Policy Editor, go to "computer configuration / Administrative templates / system / device installation / set installation restrictions", click "prohibit installation of devices that are not described by other policy settings" on the right. Select "enabled" in the interface that appears and click OK to save. In this way, even if other USB drives are connected, they cannot be accessed normally through the system, let alone copy the data to the USB disk.

If you don't log in, you won't turn it off.

If you need to leave the computer temporarily at work, the Win+L hotkey can quickly lock the computer, and you can enter the system desktop only after entering the password accurately. But vista has an inadequate design, that is, even if you do not log on to the desktop, you can choose "turn off the computer" on the login window, so that although you will not lose your personal password, it may lead to the loss of data in operation, and the consequences are also very serious. This loophole can also be plugged with Group Policy.

Open the "Group Policy Editor", go to "computer configuration / Windows Settings / Security Settings / Local Policy / Security options", double-click on the right side of "shutdown: allow the system to shut down without logging in", select "disabled" in the subsequent configuration interface, click OK and save and log out, then you can't shut down directly. Although this method can make it impossible for those who are "willing to help others" to turn off their phones directly, there is nothing they can do about savage operations such as long pressing the power button or directly cutting off the power supply.

Disable access to disk

Disk is a device that saves computer files. If users are not allowed to access the disk, the disclosure of privacy and the loss of important files can be avoided. And in order to prevent novices from deleting disk files by mistake, you can also use this technique to prohibit users from accessing the disk, open the "Group Policy Editor" and enter the "Local computer Policy / user configuration / Management template / windows components / windows Explorer" and find the item "prevent access to the drive from my computer" on the right, double-click to enter the configuration interface. When enabled is selected, you can select the disk letter that is forbidden below. When the selection is complete, click OK to save, and the restricted disk will not be accessible in Explorer.

Group policy can also be modified by personality.

The above three techniques focus more on "restrictions", that is, limiting the use of certain functions. In fact, group policy has another important role, that is to realize the personality modification of the system. We know that pressing the Ctrl+Alt+Del key will open an interface with related actions such as Task Manager and locking the computer, and the access Group Policy may also customize what this menu displays.

Open the "Group Policy Editor" and then enter the "user configuration / management module / system / ctrl+Alt+Del options", the corresponding options are included on the right, such as to delete the change password button, just double-click "Delete" to change the password, select "enabled" in the configuration interface, click "OK and save", and then press the shortcut key to become more refreshing?

The use of group policy in Vista can be achieved in the system settings and modifications there are many, here can not be enumerated.
