This article describes the subkeys located in the HKEY_CURRENT_USER registry key in Windows XP.
The information in this key is built from the HKEY_USERS key during the logon process. Therefore, all information found in the HKEY_CURRENT_USER key is a copy of the subkey HKEY_USERS\username, where username is the name of the active user (or Default).
