Registry Key

By

Definition: A key in the Windows Registry can be thought of like a file folder. A key that sits within another key is called a "subkey."

Registry keys may contain additional registry subkeys and registry values and will always exist under the highest key in the hierarchy called a registry hive.

In Registry Editor, keys and subkeys are shown as the folders on the left hand of the screen.

Also Known As: registry subkey, registry entry
Examples:
"The key I was working with in the Windows Registry had numerous subkeys and values pertaining to several Internet Explorer functions."
