You can install Leostream Connect in Shell mode by selecting the Enable Run as Shell mode task in the Installation Wizard. 

When Leostream Connect is running in Shell mode, you cannot access the Leostream Connect System tray menu. Instead, use the hover menu or the following key combinations to access Leostream Connect dialogs. (To access the hover menu, move and hold the cursor at any edge of the primary display for two seconds.)

• Ctrl-Shift-C: Opens the Connect dialog, where you can launch desktops and applications.
• Ctrl-Shift-L: Locks the client workstation running Leostream Connect, if the Allow user to lock client workstation option is selected on the Connection Broker > System > Settings
• Ctrl-Shift-M: Opens the Manage dialog, where you can manage another user’s resources.
• Ctrl-Shift-O: Opens the Options dialog, where you can modify the Connection Broker address and USB options.
• Ctrl-Shift-X: Exits shell mode.

For more information, see "Using Shell Mode" in the Leostream Connect guide. 

Shell mode is particularly handy when combined with Leostream Connect client-side passthrough. You can repurpose PCs and laptops as thin clients by allowing users to launch their remote desktops directly after logging into their physical client device. When the user logs out of the remote session, they are logged out of Leostream Connect and the physical client device and go back to the original Windows login screen. 

To enable credential passthrough, install Leostream Connect with the Enable client-side credential passthrough task selected in the Installation Wizard (see the Leostream Installation Guide for more information).
