    When updates are synchronized to your WSUS server, the metadata and update files are stored in two separate locations. Metadata is stored in the WSUS database. Update files can be stored on your WSUS server or on Microsoft Update servers, depending on how you have configured your synchronization options. If you choose to store update files on Microsoft Update servers, only metadata is downloaded at the time of synchronization. You approve the updates through the WSUS console, and then client computers get the update files directly from Microsoft Update at the time of installation.

    if you choose to store updates on your WSUS server, your WSUS server will download all those update package files and store on your WSUS server so that it can serve the update package files to your client computers. Your WSUS will download the update package files once from microsoftupdate.com

    if you choose NOT to store updates on your WSUS server, your client computers will contact your WSUS to determine needed updates+approvals, but the client computers will then be directed by WSUS to each download from microsoftupdate.com. Your client computers will all download the update package for itself (many times downloading the same files)
