Introduction
The Windows Registry is an essential component of the Windows operating system, acting as a centralized database that stores configuration settings and options for the system and installed applications. However, over time, this database can become cluttered with errors, leading to performance issues, application crashes, and even system failures. In this article, we will explore 10 proven methods to fix Windows Registry errors and boost your PC performance.
Understanding the Windows Registry
The Windows Registry is divided into five primary sections known as hives:
- HKEY_CLASSES_ROOT (HKCR): Stores information about registered applications and their associated file types.
- HKEY_CURRENT_USER (HKCU): Contains settings and preferences for the currently logged-in user.
- HKEY_LOCAL_MACHINE (HKLM): Holds settings for the local machine, including hardware and software configurations.
- HKEY_USERS (HKU): Stores information about all user profiles on the machine.
- HKEY_CURRENT_CONFIG (HKCC): Contains information about the current hardware profile.
When entries in these hives become corrupted or obsolete, it can lead to various issues, prompting the need for cleanup and repair.
