You can obtain Dynamic Update packages from the Microsoft Update Catalog. At that site, use the search bar in the upper right to find the Dynamic Update packages for a particular release. The various Dynamic Update packages might not all be present in the results from a single search, so you might have to search with different keywords to find all of the updates. Check various parts of the results to be sure you've identified the needed files. The following tables show the key values to search for or look for in the results.
