What is the registry used for? What is Group Policy? What is it used for?

The registry is actually a large database that contains the configuration of applications and computer systems, system and application initialization information, the association of applications and document files, the description, status and properties of hardware devices, and various state information and data. The registry system consists of two parts: the registry database and the registry machine.

The registry database includes three files: and, and one is in the root directory of the C drive", which is just a general framework with Windows, let's take a look at the sum first. It is used to store system information about the computer, such as information about the installed hardware and device drivers.

This file is in the windows directory. It is used to save information that is unique to each user, such as desktop settings, wallpaper or window color settings, etc. This file is also in the windows directory.

The self-backup file for the self-backup file also provides a tool for the registry: the registry, with which you can perform various tasks on the registry.

2.Group policy, as the name suggests, is a group-based policy.

It exists as an MMC snap-in in Windows and allows system administrators to set up a variety of configurations, including desktop and security configurations, for the entire computer or for specific users. For example, you can customize the available programs for specific users or groups of users, the content on the desktop, the Start menu options, and so on, or you can create special desktop configurations for the entire computer. In a nutshell, Group Policy is a set of system change and configuration management tools in Windows.

In a nutshell, Group Policy.

Most of the content is displayed in Chinese, which is more intuitive and easy to understand, and contains part of the registry content, in which general users can make relevant settings on the computer.

The registry is displayed in English, which is not easy to read, and contains all the system information and most applications.

Information. If you are interested, you can study it, but it is not suitable for general users.

Group Policy is used to modify the registry and do some administrative work. Essentially, it's no different.

In layman's terms, Group Policy is an alternative registry.

Group Policy is the graphical interface of the registry, and all the operations of Group Policy are reflected in the registry. The registry is the carrier. But modifying the registry manually is risky.

However, Group Policy is generally used for large-scale user, computer management. It is impossible to modify the registry one by one, and it is time-consuming and labor-intensive.

Group Policy is not the same as a "registry", and a "registry" can theoretically change arbitrary key values to make it more suitable for our needs. However, Group Policy only controls certain items, so in a sense, what Group Policy can do, modifying the registry must do. Conversely, modifying the registry may not be effective with Group Policy.

After installing WindowsXP Tease by default, our WindowsXP is not very secure. Therefore, we need to do some tinkering with the system, and in general, we need to use the registry. Admittedly, modifying the registry is a very effective method, but it requires a certain amount of computer knowledge, otherwise there is a high risk of causing a system crash.

However, if we pay attention to using Group Policy in WindowsXP, we can easily create a secure WindowsXP without having to resort to registry rolling.

Common Denominator: Big Potato:

All have the ability to configure the system.

Differences:1Group Policy configures the system in the form of a window, which is more intuitive; The registry configures the system in the form of data and is relatively abstract.

2.The registry can be configured in very small places; Group Policy re-alerts to the security configuration of the system, where the range of locks contained is small.

Note: The above is only obtained by personal experience.

Such. Let's give you a layman's talk.

The information in the registry is generally all the program information of the computer.

The information of the group policy is generally the service information that the computer opens, how about it, it is better than those round guesses the information from the Internet to search for the banquet cavity type.

Well understood, right? Huh

All actions should be reflected in the registry. The registry is the carrier. But modifying the registry manually is risky.

The registry is a database that stores the configuration of system software and application software in the Windows system, and as Windows becomes more and more functional, there are more and more configuration items in the registry, and many configurations can be customized, but these configurations are distributed in all corners of the registry, if it is manually configured, you can imagine how difficult and troublesome it is. Group Policy integrates the important configuration functions of the system into various configuration modules for users to use directly, so as to facilitate the management of computers.

In fact, to put it simply, Group Policy settings are modifying the configuration in the registry. Of course, Group Policy uses a more complete management organization method to manage and configure settings in various objects, which is far more convenient, flexible, and powerful than manually modifying the registry.
