After messing about with progs and changes etc, to no great purpose went on another google and found what appears to be a solution;
Run
msconfig
Startup tab
Uncheck systray
restart
repeat but check systray
And touch wood me icon seems to be back!!! Well it's survived 6 turn offs.
Thanks for the steer in the right direction.
