What is Windows Registry?

Windows registry has a tree-like structure and it is divided into three parts, they are main branches called hives, small branches called keys, and leaves called values.

Let us know about hives in brief

  • HKEY_CLASSES_ROOT - contains information about registered applications, including file associations and OLE object classes
  • HKEY_LOCAL_MACHINE - contains most settings for your hardware, OS software, and third-party applications
  • HKEY_USERS - contains all PC user settings
  • HKEY_CURRENT_USER – contains all settings and configuration information for the user currently logged on. In addition, the user’s screen colors, folders, and control panel settings are stored here
  • HKEY_CURRENT_CONFIG - contains settings for your PC’s hardware components such as display and printers

The above-mentioned list of hives are a very important part of accessing and managing information on the system. Sometimes you may come across Windows registry errors when the above-mentioned hives are attacked by virus threats or when there is a problem with the OS files. Finally, it leads to the system’s low performance. Therefore, follow below below-mentioned tricks to fix Windows Registry errors when occur.

This information may get corrupted by virus and malware threats and lead to the system’s poor performance. Hence, it is better to keep a copy of the Windows registry that would help us restore it in case it crashes.
