September Patch Tuesday Updates Out for Several Windows 10 Versions (Update Also Live for W10 Mobile)


Update: The company has now also released updates to the May 2019 Update (KB4515384 - Build 18362.356)) and the October 2018 Update (KB4512578 - Build 17763.737).

Microsoft has started releasing September Cumulative Updates for various Windows 10 versions, including Windows 10 April 2018 Update, Fall Creators Update (version 1709), Anniversary Update (1607), and the original Windows 10. The Windows maker has also released an update for Windows 10 Mobile (KB4518514 - Build 15254.587).

The release notes aren't yet available for the October 2018 Update and the Creators Update; we will update this space when today's patches are made available for these two versions. The latest Windows 10 May 2019 Update also hasn't received any fixes today, but it is likely that the company will deliver these updates later today.
