How Software Update Services (SUS) Works

The 5 steps below outline how SUS functions in terms of obtaining updates and deploying them to AU client systems:

1. The SUS Server will synchronize with Microsoft’s Windows Update Servers and downloads all new or missing patches.
2. At this point, the Administrator has an option to APPROVE the new patches, or may opt to test the patches prior to approval.
3. Once a patch is approved, AU clients will check in for any new updates.
4. If an AU client finds any new updates, it will download and install those patches (based on its client configuration settings).
5. Once the patches are installed, then the logged in user is given an option to reboot (only if necessary).
