Microsoft releases new security updates for its products at least once a month. In most cases, the Windows Update service does a great job of automatically getting and installing updates in Windows. However, if needed, you can manually find, download, and install the latest cumulative update for your version of Windows from the Microsoft Update Catalog. This can be useful for computers with the wususerv service disabled (or custom Windows Update Group policy settings), for environments disconnected from the Internet (if you are not using a local WSUS server to manually approve and deploy Windows Updates), and for local networks with metered connections, etc.
