Reboot pending

Hi,

How do Windows Update Agent check for when a reboot is pending. I have a lot

of clients which needs to be rebooted, for WSUS to know that the lastest

patch are installed.

I have checked kb832475 regarding:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session

Manager\PendingFileRenameOperations

and

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates\UpdateExeVolatile

and none of the clients have any of these registry keys.
