No New Windows Update Offline Scan File for Windows 10 1809 Until January 2019

As most are packing up to head home for the Christmas holiday, there’s a tidbit of information that may have been overlooked when Microsoft delivered its December 19 cumulative update for Windows 10 1809 to solve an actively exploited bug in Internet Explorer.

Per KB4483235:

For customers using Windows Update offline scan file, Wsusscn2.cab, no new December scan cab will be issued. You will need to download the December 2018 WSUS scan cab and then manually download this KB from Microsoft Update Catalog to deploy. An updated scan file that includes this KB will be available in the next security release in January 2019.

A Delta package for this update will not be available. Customers using Delta package updates need to apply the Full Update. Customers who do not apply the Full update, and only the December Delta package update from December 11, 2018 will experience an update failure when installing the January Delta Update. The January Full update will install correctly.
