Windows 10: Microcode Updates (March 13, 2019)

This Microsoft website, dated Nov. 2018, contains an overview of the available updates. However, the KB articles linked below have not yet been updated, but show the revision status of January 2019.

• KB4100347 for Windows 10 V1803
• KB4090007 for Windows 10 V1709
• KB4091663 for Windows 10 V1703
• KB4091664 for Windows 10 V1607
• KB4091666 for Windows 10 V1507

However, if you search the Microsoft Update Catalog for the KB numbers, the updates will be offered with the date 13 March 2019. Since the documentation has not yet been updated, it is unclear what has changed. And I got a German comment, that the downloads offered via Update Catalog hasn't been changed. (via deskmodder.de).
