Unwanted Spark Updates

I have installed the wildfire Server and 20 spark clients in a small windows 2003 / XP network. The users have no rights to install anything on

their clients. Is it possible to turn out the automatic update announcement of spark on the client machines? Thanks in advance for your answer(s).

Use Spark Manager to define your version
