Today I installed 24 "critical" updates for Windows 7. After rebooting, my secondary monitor is not detected. It is not showing up in the control panel screen resolutions settings dialog, or device manager. The NVidia Control Panel cannot find it with the "Rigorous display detection" button available from the "my display is not found link" in "Set up multiple displays".
I have powered down everything, unplugged the monitors and plugged them back in etc.
Here is the list of updates installed (nothing seems related to video):
Has anyone else had this problem? How can I solve it?

Did you try reinstalling the NVidia driver without the second monitor connected?
Restart, then try and connect it back up.
