It took Microsoft a bit longer than expected but KB4284848, a new cumulative update for Windows 10 version 1803, has finally been released.

Microsoft released cumulative updates for previous versions of Windows last week but did not release an update for the April 2018 Update version.

It is usually the case that updates get released for all versions of Windows 10 and that is why it was strange that 1803 did not receive one when all other versions did.

Windows users and admins can install the update using Windows Update or the Microsoft Update Catalog. Note that Windows Update does not pick up the KB4284848 yet.

If you use the Microsoft Update Catalog to download the update you need to install the servicing stack update KB4338853 first. Microsoft rated the update critical.
