When I start, I get an alert that resarting my computer is necessary before updating can continue (several months now). Trying to load Nero, I get alert that there is a panding reboot that needs to happen before it can load. Did not get this when I recently loaded Norton. Windows Update on AUTO, and manually running it indicates I am current. So, somewhere it seems there is a reboot order not getting cleared when I restart or even shutdown totally.
