The Windows Registry is a hierarchical database that stores low-level settings for the Microsoft Windows operating system and for applications that opt to use the registry. The kernel, device drivers, services, Security Accounts Manager, and user interface use the registry. Without Registry, you can not imagine your Windows operating system. Windows Registry contains all information about settings, options, and other values for all programs and hardware installed on Windows operating systems. For example, when a program is installed on a computer, a new sub-key containing settings, program’s location, version, and how to start the program are added to the Windows Registry. While executing any program on the computer, it accesses the Registry file and operates correctly.
Once Registry gets corrupt, your Windows will stop working. Hence, before making any changes in your computer registry, you should take a backup of the Registry file. In this post, we will learn to create backup/restore Registry keys on Windows 10/8/7.
Once you have a backup of Registry and something goes wrong, you can revert with backup by restoring to the original path.
There are two ways to take the backup of Registry: Full backup of Registry or backup only individual keys.
