What is a registry that is used to generate programs

The registry is an internal database of Windows, a giant tree-like hierarchical database. It records the interrelationships of the software that the user installs on the machine and each program; It encompasses the hardware configuration of the computer, including plug-and-play devices that are automatically configured and various devices that are already available. The registry plays a central role in the system by storing parameters that directly control the boot of Windows, the loading of hardware drivers, and the running of some Windows applications.

It includes: 1) configuration and state information about software and hardware, and the registry holds the initial conditions, preferences, and uninstall data of the application and explorer shells.

2) The entire system settings and various licenses of the networked computer, the association of file extensions with applications, the description, status and properties of hardware components.

3) Performance records and other underlying system status information, as well as other data.

If the registry is corrupted, it can cause the Windows boot process to be abnormal, or it can lead to a complete system breakdown. Therefore, it is very important for Windows users to correctly understand and use, especially to back up in time and restore the registry in case of problems.

On the machine, start Run Enter regedit, and go see for yourself

The methods that can be used to write a program to the registry are:You can type regedit in the start menu in Runtime, or you can type regedit in DOS and you can use the registry.

Program registry root key description:The hkey classes root contains all the OLE information and document types registered.

Copied from hkey local machine software classes.

The hkey current user contains the logged-in user configuration information, which is copied from the hkey users subtree.

The hkey local machine contains the configuration information of the machine. The :config subtree is the display printer information.

The enum subtree is the plug-and-play device information, and the system subtree is the device driver.

and the control set of service parameters.

The software subtree is the application.

PassedRegistryThe backup registry method is:Since modifying the registry sometimes compromises the security of the system, whether it is Windows 98 or Windows 2000 or even Windows XP, the registry is put in"Hidden"In a very secluded place, to think"Please"It has to go through special means.

Click"Get started"menu, select on the menu"Run"option in the pop-up"Run"window"regedit", click"OK"button, so that the registry is launched.

Click on the registry"Registry"menu, and then click it"Export the registry file"option, enter a file name in the dialog box that pops up"regedit"。

will"Save type"Selected as"Registry file"and then will"Export range"Set to"All", select the file storage location, and finally click on it"Save"button to save the system's registry to your hard drive.

Once you have completed the above steps, locate the folder where you just saved the backup file.

You will find that the backed-up files are already in the folder.

The registry in the computer is the core database of the Windows operating system, which stores various parameters and directly controls the startup of Windows, the loading of hardware drivers, and the running of some Windows applications. It can be said that it is the nerve center of Windows.

In the registry, all the data is organized in a tree-like structure with keys and subkeys, much like a directory structure. Each key contains a specific set of information, and the key name of each key is related to the information it contains. If this key contains a child key, there will be a "+" symbol on the left side of the folder representing this key in the registry window to indicate that there is more content in this folder.

If this folder is opened by the user, then this "+" will become "".

The registry manages various information through keys and subkeys. However, all the information in the registry is saved in various forms of key-value data. In the right pane of the registry, key-value key key data is saved. These key-value necklace key data can be divided into three types:

1.String value.

In the registry, the ruler string value is generally used to represent the description of the file, the identification of the hardware, and so on. Usually it consists of letters and numbers, and the maximum length cannot exceed 255 characters.

2.Binary values.

In the registry, binary values are unlimited in length and can be any byte long. In the registry, binary is displayed in hexadecimal format.

Value. The dword value is a 32-bit (4-byte, i.e., double-word) value. In the registry, the system displays the dword value in hexadecimal fashion.

The registry has the ability to force changes to the system. Like the system's interface settings, NTFS permissions, group policies, service status, etc., are controlled by it, which is a collection of record settings, and is a library file.

To give a few examples, USB flash drive viruses always make it impossible for users to view hidden folders and files, that is, through the registry, so that users cannot change them through the folder options, because the registry has a higher priority and can be set to force.

For example, some programs and viruses are not launched by boot scripts, let alone in the "All Programs"-"Startup" folder, but by hkey local machine software Microsoft Windows CurrentVersion Run

Add the string to the boot startup (there are other places to do so, of course).

Also, what software we have installed, which software has not been registered, what can be tried for how many days, how many times to try it, etc., this information is often stored in the registry.

Start -- Run.

Enter regedit

The registry is equivalent to our ID card, and many settings of some software are stored in the registry, especially the settings of the operating system. Therefore, modifying the registry can directly modify the system settings, but do not modify it at will, so as not to cause the system to crash.

The registry (called login in Chinese traditional Windows) is an important database in Microsoft Windows that stores system and application setup information. Registries have been around since Windows introduced OLE technology. The subsequent introduction of Windows NT was the first operating system to make extensive use of the registry at the system level.

However, it was not until Microsoft Windows 95 that the registry really became a regular part of Windows users' exposure and continues to be used in subsequent operating systems. See.

The registry is a core database in the Windows operating system, which stores various parameters, directly controls the boot of Windows, the loading of hardware drivers, and the running of some Windows applications, so as to play a central role in the whole system. These functions include configuration and status information related to software and hardware, such as the initial conditions, preferences, and uninstall data of the application and explorer shells stored in the registry, the overall system settings and various licenses of networked computers, the association of file extensions with applications, the description, status and properties of hardware components, performance records and other underlying system state information, and other data.

Specifically, when Windows is started, the registry will check the new hardware information against the existing hardware residual parts configuration data; The system kernel selects information from the resistry, including what device drivers to load, and in what order, and the kernel sends back its own information, such as the copyright number, etc.; At the same time, the device driver also sends data to the registry and receives load and configuration parameters from the registry, a good device driver will tell the resistry what system resources it is using, such as hardware interrupts or DMA channels, etc., and the device driver will also report the configuration data found; Provide a service for the operation of applications or hardware that adds new configuration data. With the ini file compatible with 16-bit windows applications, when installing a one-based application, the application's installer setup as in windows creates its own ini file or creates entries in and files; At the same time, Windows also provides a large number of other interfaces that allow users to modify system configuration data, such as control panels, setup programs, etc.

If the registry is corrupted, it can cause the Windows boot process to be abnormal, or it may lead to the complete collapse of the entire Windows system. Therefore, it is very important for Windows users to correctly recognize, use, especially timely backup and restore the registry if there is a problem.

The rebook table is an internal database of Windows, which is a system management database designed by Microsoft specifically for its 32-bit operating system. The registry plays a central role in the overall system by storing various parameters that directly control the startup, the loading of hardware drivers, and the running of some applications. If the registry is compromised, the startup will run abnormally, and the entire system will be paralyzed.

RegistryIt's the system.

And some software-related information, some system configurations and software configuration destruction information are in it, and some data, such as reg

Put your third-party software into the root directory of the program, that is, the directory where you want to start the program, and then run it, and the greening is completed after the operation, without having to get the registry.

The registry is the lifeblood of Windows, which stores a large amount of system information, and to put it bluntly, it is a huge database. If you don't know what a database is, that's fine, it doesn't affect your knowledge of the registry, but it's a good idea to know about databases. All the information in the registry is usually managed by the Windows operating system, and can also be modified through software or manually.

The registry contains a lot of important information about the system, including peripherals, drivers, software, user records, etc., and the registry largely "directs" how the computer works.

The registry is very useful, very powerful, and is the core of Windows. By modifying the registry, we can throttle, optimize, and so on on the system. For example, if we don't want others to use the Start menu, we can modify the registry to achieve this purpose.

In addition to this, there are many more, you can refer to this manual to revise, it is very detailed and enriched over time. The main thing about revising the registry is to practice, observe carefully, think carefully, and you will slowly master it.

In particular, it is worth mentioning that learning knowledge is for application, so it is not required to memorize every command, because there are too many, and it is easy to forget after a long time, and this is not an exam, relax, hehe. You just need to know how to modify it and use it proficiently.

It's better not to touch anything. Be careful.
