Property Value

If true, updates are stored on Microsoft Update (WSUS downloads update metadata and license agreement only); if false, updates are downloaded and stored on the local server.

Storing update files locally on the WSUS server can save bandwidth on your Internet connection, because clients download updates directly from a WSUS server. This option requires enough disk space to store the updates that you intend to download. A minimum of 30GB of hard disk space is recommended.

Storing update files on Microsoft Update and having clients download only approved updates is useful if you have mobile clients, branch offices, or any situation in which clients have a direct connection to the Internet, and downloading updates over a WAN connection would introduce additional complexity. With this option, only approvals are distributed over the WAN link. Also, when you synchronize with Microsoft Update, you will get only update metadata, which describes each of the available updates. The update files themselves are never downloaded and stored on the WSUS server.

To download only approved updates, set HostBinariesOnMicrosoftUpdate to false and DownloadUpdateBinariesAsNeeded to true.

WSUS ignores the following property values if HostBinariesOnMicrosoftUpdate is true:
