Microsoft releases KB4501375 for Windows 10 version 1903

It always takes a bit longer before the second cumulative update of a month is published by Microsoft for the current version of Windows 10.

The company changed the update testing and release strategy some time ago after the Windows 10 version 1809 release fiasco to test updates in the release preview ring before they are made available to all devices running the version of Windows.

Microsoft released the cumulative updates KB4501371 and KB4503288 for Windows 10 versions 1809 and 1803 on June 19, 2019, and the updates KB4503277 and KB4503283 for Windows 7 and 8.1 on June 21, 2019.

Note: KB4501375 is considered a preview update, not a final update. It should not be installed on production machines but is suitable for testing purposes. In any case, make sure you create backups before you install the new version.
