The local settings are stored in the hard disk and these settings acts as a blueprint of the actual settings. The settings are saved under HKEY_LOCAL_MACHINE that refer to the local machine settings and it includes those settings that are currently being used. As soon as the user uses Groupware sync then these settings gets transferred to HKEY_CURRENT_USER, which stores the setting user wise. This way multiple users can use the same machine but, it doesn’t allow seeing each other’s local settings when moving from one user to another.
