thank you and Søren for the quick response, I did
a little bit search and managed to code something
similar to you both suggested:

 username=getenv('USER'); % for Linux/Unix/Mac OS
 if(isempty(username))
    username=getenv('UserName'); % for windows
 end
 if(~isempty(username))
    username=['session-' username];
 end

getenv('UserName') enables this for windows machines.
