USB drive version versus downloaded files.
From what I've seen, the downloadable Windows 10 image typically receives updates through official channels, though not necessarily on a frequent schedule. Purchasing the USB key usually means you get the latest version available at release, but occasional patches may be applied depending on support needs. It's generally designed for stability and security rather than constant changes.
Previously, only updates for larger patches were released, such as Service Packs. It seems the current approach remains consistent. Recent updates include Anniversary and Creators versions. You might also find a more comprehensive update on the stick, though this isn't guaranteed unless the patch has been available for several months.
