How to detect programmatically when the "Install Updates and shut down the computer" shield icon is present on top of the Start / "Shut down" button?

Question

Some updates put that little shield indicating that the computer needs to be rebooted. Is that shield a registry key? I thought it was the key:

HKLM\System\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations

Source: http://technet.microsoft.com/en-us/sysinternals/bb897556.aspx

But my computer is showing the icon right now, and there is no PendingFileRenameOperations in the registry, so obviously it's something else, or a combination of things !?

You can use the Windows Update Agent API to find if a reboot is currently required to complete an update.

I'd say this is not exactly what the question asks. The question asks (more or less) how to see if there are pending updates to install. – Vinko Vrsalovic Nov 06 '09 at 19:39
