I would like to learn more about the computer registry and what it does, and how to learn about it

Fix it with Super Bunny or Optimizer.

I don't think we need to learn these things at all, except for professional computer scientists, because there are so many project names involved that we don't need to figure out every key, and if we do, we don't know how much time it will take to memorize.

In general, we don't need to manually modify the registry, modifying it is just to implement some functions, and now we are full of software to help us modify the registry, and it is easy to find one to achieve the purpose.

For the registry, personal computers often use only a few boot loads, and some simple settings of the system.

If you use it a lot, you'll naturally remember these settings, so there's no need to deliberately memorize them, and of course if you're proficient in the registry, that's also a good thing, and many of the settings can be easily solved through the registry.

You can easily get rid of a Trojan horse.

If you're interested in it, you'll learn naturally.

Back it up and do it yourself.

The registry is the foundation of the system, and it stores many things related to system configuration and applications. Very important for the system. Therefore, it has also become a place where viruses and others like to start. The registry is very boring, but learning it is also very helpful for yourself.

The registry is a database of the Windows system that stores information about the configuration of a computer, including settings for how the system needs to be called when it is running. The items included in the Windows registry are: each user's profile, the programs installed on the computer and the types of documents that each program can create, the property settings for folders and program icons, the hardware in the system, the ports being used, and so on.

The registry is a core database in the Windows operating system, which stores various parameters and directly controls the boot of Windows, the loading of hardware drivers, and the running of some Windows applications, thus playing a central role in the entire 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 configuration data. The system kernel selects information from the registry, including what device drivers to load, and in what order, and the kernel transmits its own information, such as 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, and a good device driver tells the registry what system resources it is using, such as hardware interrupts or DMA channels.

In addition, the device driver reports the configuration data it finds; A service that adds new configuration data to the operation of an application or hardware. Compatible with 16-bit Windows applications with INI files, when installing a Windows-based application, the installer of the application is set up like in Windows - creating its own INI file or creating 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 Windows registry is a set of data files that help Windows control hardware, software, user environment and Windows interface, and the registry is the core "database" of the Windows 9X Me NT 2000 operating system, hardware devices and customer applications to run normally and save settings; is a huge tree-like hierarchical database. It records the interrelationships of the software that the user installs on the machine and each program; It contains the hardware configuration of the computer, including the plug-and-play device that is automatically configured and the various device descriptions that are already available, the status attributes, and the various status information and data.

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.

It stores the configuration information of the Windows system, and the system and various software decide how to configure themselves according to the parameters set in it when they boot up.

It is used to manage the software, settings, and various system components in the computer.

lock bios:

First find the option with password in the BIOS, there are usually two, one is the user password, the other is the supervistor password, the former is the user password, you can only change the time when you log in to the BIOS with the change password, and the supervistor password is the administrator password, you can change the BIOS at will.

When the default password is set, move the cursor to SuperVistor Password Enter, enter the new password (if there is an old password, enter the old password first, and then enter the new password), press Enter, and then enter the new password, and you're done. Then press F10 to save the settings!

1.Click Start, click Run (or press the shortcut key Win+R), enter regedit in the pop-up Run dialog box, and click OK.

2.In the open registry, click File in the menu bar and select Import from the file options that pop up. (The first two steps are actually the same as when exporting registry information, but the import and export are different).

3.In the open Import Registry, find the complete and functioning registry file that you have saved, and select Import. That's it.

The steps to add the PC registry are as follows:

The materials we need to prepare are: computer,

1. First of all, we turn on the computer, click to open "Run" in the start menu in the lower left corner, and then click to enter "regedit", and press enter to confirm.

2. Then we click to open the "Import" in the file in the upper left corner of the pop-up window.

3. Then we click to open the desired registry in the pop-up window.
