How to Backup Windows Registry.
The Windows registry is a vital operating system database that stores critical configuration settings, preferences, and information about installed applications, hardware, and system components. For this reason, any incorrect changes or alterations to the registry can have a significant impact on Windows stability and performance.
The registry is accessed and modified through the Windows Registry Editor utility (regedit.exe), which allows users to view, create, modify, and delete registry keys and values. However, it is recommended that you create a backup of your registry, or a restore point before making any changes to the registry.
