Windows Vista SP1 installs MSTSC.exe version 6.0.6001.18000 on to your computer, the only way to discover this information is to browse to the MSTSC.exe file in explorer which is located in the c:\windows\system32\ directory. Right click on MSTSC.exe and select properties, then select the "Details" tab
You can find all these startup commands by running "MSTSC /?" from the run command, and because Microsoft in all their wonder only outputs this data in a screen where you cannot copy the text from (unless you know the trick) I have posted the output here for you to use as you see fit.
OUTPUT FROM MSTSC /? Command:
"connection file" -- Specifies the name of an .rdp file for the connection.
/admin -- Connects you to the session for administering a server.
/f -- Starts Remote Desktop in full-screen mode.
