Quote:Today is the second Tuesday of the month, making it Patch Tuesday. That means that there are cumulative updates available for all supported versions of Windows. The amount of supported versions goes up by one today, as version 1909 was released. Today also marked the end of support for version 1803, but only for Home and Pro SKUs, so there are still updates for Enterprise and Education.
 
Moving forward, versions 1903 and 1909 will get the same updates, since it's just an enablement package that increases the build. Today's update is KB4524570, and that brings the build number to 18362.476 and 18363.476 for versions 1903 and 1909, respectively. You can manually download it here
