While I have spotted it being available from Windows Update, as it has just started rolling out it may take some time to be available in all regions. > This update is titled "2019-04 Cumulative Update for Windows 10 Version 1809 for x64-based Systems (KB4495667)" and is the second Cumulative Update released this week, with KB4501835 released two days ago.
