Workspace Preferences is the users' desktop management system. It offers users several options, such as configuring their desktop and their Quick Launch icons, starting applications automatically, and swapping mouse buttons. But it also provides information that can be useful for troubleshooting (e.g. LDAP entries, Active Directory group membership, current Zones, and the connection state of the machine the user session is running on).
In the Workspace Control Console, you can determine which options should be available in the users' Workspace Preferences. This allows you to make certain options available or unavailable according, for example, to company policies. These user settings are stored in pwruser.ini, located in \Personal Settings in the user's home folder.
