How to download cumulative update for Windows 11?

Note that these are not full installers but individual update packages. Here's how to download a cumulative update for Windows 11 manually:
- Open Microsoft Update Catalog.
- Search for the Windows 11 update you need. (For instance, if the cumulative update KB5070311 is an available update shown in the Settings > Windows Update page but can't be installed through the usual means, you can search for KB5070311 to download it.)
