The effect on the Registry is exactly the same as removing or adding a gear in a giant machine.If the impact is wrong, the system may be completely paralyzed.

The registry is considered a 'supreme key' to penetrate Windows and is almost exclusively for high professionals. For the average user, the Windows Registry is almost a "forest" with almost no exit. We would like to summarize some of the Registry knowledge for your reference.

1. Some basic knowledge about the Registry:

The Registry is a database used to store all Windows specifications. It records all information when you change or edit in the Settings Menu, Control Panel and so on

In Windows 95 and Windows 98, the Registry is saved in two files: user.dat and system.dat in the Windows folder. In Windows Me, the Registry is stored in the Classes.dat file in the Windows folder. In Windows 2000 and Windows XP, the Registry is saved in the ' WindowsSystem32Config ' folder.

You can edit the Windows Registry by using the Registry Editor available in Windows by going to the Run window and typing ' Regedit '.

The registry has a tree-like structure, similar to the structure of a directory tree with many sub-branches radiating depending on the application structure. Usually the Windows Registry has five main branches, each of which takes care of storing specific information. Each main branch emits many sub-branches and these sub-branches also store a wealth of specific information about everything that is in Windows.

HKEY_CLASSES_ROOT: Save shared information for the entire system.

HKEY_CURRENT_USER: Save information for users who are using or logging into Windows.

HKEY_LOCAL_MACHINE: Save system, hardware, software information .

HKEY_USERS: Save the information of all users (users), each user is a branch with the name of the format ID of that user.

HKEY_CURRENT_CONFIG: Save information about the current hardware in use.

Those who are proficient in Windows who want to gain a deeper understanding of the system need to learn as much about the Registry as possible for the following reasons:

- Registry stores all information about the hardware, software, user options . controlling the contents of the Registry is an indispensable requirement for you to use the computer in a scientific, deep-rooted way. more about the Windows environment.

- Want to go further in Windows-based programming techniques, security, even unlocking software or breaking into other people's computers . then you need to have a certain understanding of the Registry.

- Most of the tricks in Windows that popular computer magazines have posted are closely related to the Registry. The tools can affect Windows created by software circles, most of which are based on 'infiltrating' the Registry with more user-friendly and intuitive tools.

2. Warning when using Registry Editor

Everything that exists in a Windows system leaves an extremely important "password" or key in the Registry. The impact on these keys may only affect a small part of Windows, but sometimes affect the entire system. When "incorrectly" correcting a few important "keys" can make Winsows paralyzed or completely damaged.

When you 'dared' to hack into the Registry Editor it is imperative that you first back up your Registry by running Registry Editor -> File -> Export and saving this .REG file to a safe place if If corrected, it will still restore the system. When you want to restore the original Registry, go back to Registry Editor -> File -> Import -> Find the saved .REG file to proceed with the recovery.

3. A few notes when editing the Registry

- The text behind the words: User Key , Sytem Key , or Key indicates the path to the branch to be repaired or created if it does not exist. Note that the User Key is for that change to work for the logged-on user (Logon); System Key is for that change to work for all users.

- The Name line is the name of the key to be created, it is a sub-branch on the right window of the Registry.

- The Type line is the data type of the newly created key.

- Value line is the value of the key.

After backing up the original Registry and knowing how to recover, you can almost comfortably 'roll' the Registry. To become an 'expert Registry' is not really that difficult, you just need to have an English capital enough to read and understand everything that Microsoft has presented in English in Windows.

Once you have understood all the words in the Registry, you can go to 'dab' by modifying the default parameters with your parameters, then save the Registry, exit the User account, log in. re-enter the account that has been edited, access the modified item to see its effect. If it is too fast, too slow or . completely paralyzed, you should re-enter the Registry to adjust it back to the old parameter. If you cannot remember the parameters that have been modified, proceed to restore the original Registry.
