How to get window title of remote desktop

Any one has following experience?

We have a bot which is close all windows before start to log in to SAP. basically it is using key stroke ALT F4 in active window after getting the window title . it is working fine in local physical computer (laptop) but it has problem when working with virtual machine. it will automatically close the remote desktop window (i.e. close the connection of VM).

Thanks for any advice.
