4.13.4. Windows connector may hang at the Windows welcome screen when connecting to a Windows 2008 R2 server

This hang is due to the multi-monitor enumeration process that occurs between the server and the Windows connector, and it is caused by the Windows server not sending monitor layout data to the Windows connector.

Workaround: Disable the multi-monitor enumeration process using the uttsc -X off command.
