­­What is a Registry in Windows?

Registry Editor is a tool to modify registry keys and registry values in windows operating system. But, before going on registry editor, it is important to understand about what is a registry. In simple words, Registry is a collection of databases of configuration settings for windows operating systems (xp, 7, vista, 8, 8.1, 10, 11 etc). The Windows Registry stores much of the information and settings for software programs, hardware devices, user preferences, and operating-system configurations. The registry is the most important part of a Windows operating system.

For example, when a new program is installed, there are many information is going to be stored in registry (in specific location for the program). Like location of installed program and files, program behaviour, file references, program instructions etc. Set of these types of information is known as registry.
