Use User Home Directory Maintenance to change Pwruser.ini
Users can partly determine the behavior of their Workspace Control session by changing settings in their Workspace Preferences tool. These user settings are stored in pwruser.ini, located in \Personal Settings in the user's home folder. The pwruser.ini can also be changed from the Workspace Control Console using Home Directory Maintenance.
Example:
