Regedit

Regedit, short for Registry Editor, is a tool in Windows that allows users to view and modify the system's registry—a database that stores settings and options for the operating system and installed programs. Think of it as a centralized control panel where configuration details are stored in an organized manner. By editing the registry, advanced users can customize Windows behavior, troubleshoot issues, or improve performance. However, because it directly affects system functions, incorrect changes can cause problems, so it’s important to use Regedit carefully and ideally with proper knowledge.
