You can have multiple desktops available for you to use. For example, you might have separate desktop roles for managing Exchange and SQL Server that grant different rights. After you create a desktop for each role, you can switch between desktops by clicking the Centrify icon, then selecting the desktop you want to use. You can also set up hot keys to switch between desktops using a keystroke combination.
When you are finished working with a desktop, you can click the Centrify icon, then select Close Desktop.
