There are two components to managing protection updates - where the updates are downloaded from, and when updates are downloaded and applied. This topic describes where you can specify the updates should be downloaded from, also known as the fallback order. See Manage Windows Defender Antivirus updates and apply baselines topic for an overview on how updates work, and how to configure other aspects of updates such as scheduling updates. There are five locations where you can specify where an endpoint should obtain updates.
Typically, you would configure endpoints to individually download the updates from a primary source, followed by the other sources in order of priority based on your network configuration.
Updates will be obtained from the sources in the order you specify. If a source is not available, the next source in the list will be used. When updates are published, some logic will be applied to minimize the size of the update. In most cases, only the "delta" or the differences between the latest update and the update that is currently installed on the endpoint will be downloaded and applied. However, the size of the delta depends on:.
The older the updates on an endpoint, the larger the download. However, you must also consider frequency versus size - a more frequent update schedule may result in more ad hoc network usage, while a less-frequent schedule may result in larger file sizes.
Microsoft Update allows for rapid releases, which means it will download small deltas on a frequent basis. This ensures the best protection, but may increase network bandwidth. The size of the updates may be slightly larger than the frequent release from Microsoft Update as the delta, or differences between the latest version and what is on the endpoint will be larger.
This ensures consistent protection without increasing ad hoc network usage although the amount of data may be the same or increased as the updates will be fewer, but may be slightly larger. You can, however, set the number of days before protection is reported as out-of-date.
Each source has typical scenarios that depend on how your network is configured, in addition to how often they publish updates, as described in the following table:. If you set WSUS as a download location, you must approve the updates - regardless of what management tool you use to specify the location.
You can set up an automatic approval rule with WSUS, which may be useful as updates arrive at least once a day. The procedures in this article first describe how to set the order, and then how to set up the File share option if you have enabled it.
Double-click the Define the order of sources for downloading definition updates setting and set the option to Enabled. Enter the order of sources, separated by a single pipe, for example: Double-click the Define file shares for downloading definition updates setting and set the option to Enabled.
Enter the file share source. If you have multiple sources, enter each source in the order they should be used, separated by a single pipe. Use standard UNC notation for denoting the path, for example: If you do not enter any paths then this source will be skipped when the VM downloads updates. This will set the order of file shares when that source is referenced in the Define the order of sources Our new feedback system is built on GitHub Issues. Read about this change in our blog post.

There are no open issues. You want your endpoints to connect directly to Microsoft Update. This can be useful for endpoints that irregularly connect to your enterprise network, or if you do not use WSUS to manage your updates. You have non-Internet-connected devices such as VMs. You can use your Internet-connected VM host to download the updates to a network share, from which the VMs can obtain the updates.
You need to download the latest protection updates because of a recent infection or to help provision a strong, base image for VDI deployment. This option should generally be used only as a final fallback source, and not the primary source.
