3.Go to the "Compatibility" tab.

I have multiple sessions to the same computer with different credentials, but it always uses the last one I entered.

This issue stems from the fact that the Windows Credential repository holds only one entry per Windows user for a remote computer. If you use the Embedded (tabbed) display mode and store the password in the database, you'll be able to work around that limitation.


The Windows shortcuts are being performed in the session but always on my computer.

You must configure the Keyboard setting in the Local Resources tab of the session settings. You can select "On the remote computer" or "In full screen only" according to your personal preferences.
