What is Registry?

Windows registry is the spinal cord and brain for the system, a huge database that stores the system’s settings and options, including software, hardware, preferences, user and other settings, the information which devices attached to the computer and which drivers should be used with them, file associations (which programs should be used to open certain types of files). All system changes are reflected in the registry: installing software, Control Panel settings changes and other manipulations. Every time you change audio level, modify display settings, change window size, makes entries or adds keys to the registry

Where is Registry Located?

In Windows NT/2000 the database files is located in the %SystemRoot%\System32\Config directory. In earlier versions on Windows (95, 98) the registry was contained in 2 files file called SYSTEM.DAT and USER.DAT. Windows Me uses an additional file called CLASSES.DAT. Important! Registry files cannot be edited directly. You’ll need a special tool commonly referred to as “Registry Editor” to modify the registry.
