I. What is the registry, and why is the registry corrupted?

The registry is an important database in Microsoft Windows for storing system and application setting information. The Windows Registry can be thought of as a large database that contains options, settings, information, and other values for hardware and programs installed on all versions of the Microsoft Windows operating system. There are two basic elements in the registry: keys and values. To change hardware, install new software, or open programs, the operating system will always refer to the registry for relevant keys and values.
Since the registry covers almost all the data involved in computer operation, what are the reasons for the registry damage? It roughly includes the following aspects:
● Malware or virus attack
● Fragmented registry, which usually happens when you delete or update some parts of the software
Improper system shutdown (unexpected shutdown, forced shutdown, etc.)
After understanding the possible causes of registry damage, in order to avoid data loss during the process of repairing errors, it is recommended that you first use a professional data backup tool to back up important data in time. Then use a series of conventional methods to solve the problem of registry damage. Let’s first understand the method of backing up data.
