Registry branches (hives) of interest:
HKEY_LOCAL_MACHINE - Changes made here apply on a machine wide basis, and affect all users, unless it is specifically over-ridden by a change in HKEY_CURRENT_USER, in some cases. Current user settings cannot always over-ride Local Machine settings.
HKEY_CURRENT_USER - This branch of the Registry affects the currently logged on user, just as the name implies. Changes made here will only affect the active logged on user. Some settings may over-ride the LOCAL_MACHINE settings, and others will not.
HKEY_USERS\.Default - This branch of the registry is used to store Default settings for all new user accounts that are created. Any change made here will apply to any accounts created after the change was made, but will not apply to accounts that already exist. This is a handy method for an Administrator to apply specific changes to all users other than themselves.
Note: By default, the HKEY_CLASSES_ROOT and HKEY_LOCAL_MACHINE branches can only be changed by an Administrator level user. This can be changed by adjusting the "permissions" of the branch or subkey in question.
