We have a WSUS environment set up that is working correctly on most computers. It installs updates at 4PM then will start a 30 minute countdown timer for restart if it is required. This is working correctly. On one Windows 7 Dell Laptop, the countdown timer will not become the active window. If there is another application open ( I tested with Notepad) the user will not see the notification because it is behind the open application window. If I close notepad, I will see the notification timer.
This is obviously causing problems because the computer is getting restarted without the user knowing.
I don't think this is a windows update problem, but some type of display issue on the laptop. Not sure where to look though.
