I have a gpo for windows update, that clients install updates when the client shutdown. I see that the windows update installation starts, but after some seconds then the client shutdown.

In the WindowsUpdate.log I see the that the policy changed (I think this a unload from ZCM policy) and the Windows updates stop with "Exit code = 0x8024000B".

Is this problem known or is there a better way to deploy windows updates?
