 ## Update sources supported
 
 **Windows**: [Windows Update Agent (WUA)](/windows/win32/wua_sdk/updating-the-windows-update-agent) reports to Microsoft Update by default, but you can configure it to report to [Windows Server Update Services (WSUS)](/windows-server/administration/windows-server-update-services/get-started/windows-server-update-services-wsus). If you configure WUA to report to WSUS, based on the last synchronization from WSUS with Microsoft Update, the results in Update Manager might differ from what Microsoft Update shows.
