After updating windows which came through an hour ago, Start 11 does not work anymore. it does not override the start menu and taskbar.
Is the Start11 service running \ set to automatic?
If not, and you start it, log out\in, does it work then?
If not, and you reboot, does it work then?
If not, is the service still 'running' and 'automatic'?
