How do I force a PC to perform a SUS update immediately?

During normal operations, the Automatic Update client will check-in to the SUS Server every 17 to 22 hours to detect approved updates. It is possible to force the detection process by completing the following:

1. Stop the "Automatic Updates" Service
2. Check that the "AUState" registry value, located at: HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update is set to "2".
3. Delete the "LastWaitTimeout" registry value, located at: HKLM\Software\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update.
4. Start the "Automatic Updates" Service.

The Automatic Update client will begin the update detection process in approximately 10 minutes.
