Windows Registry

The Windows registry is a database which stores settings and options for the operating system for Microsoft Windows 32-bit versions, 64-bit versions and Windows Mobile. It contains information and settings for all the hardware, operating system software, most non-operating system software, users, and preferences of the PC and so on. Whenever a user makes changes to “Control Panel” settings, or file associations, system policies, or installed software, the changes are reflected and stored in the registry.
