Microsoft released July's second batch of Windows 10 cumulative updates last week for several versions of the operating system. Its latest Windows 10 version 2004 (May 2020 Update) is getting this set of updates today.

The second batch focuses on non-security updates that are optional, tagged as "Preview," and come as part of the non-optional updates with next month's Patch Tuesday updates. A bit confusing, yes... Today's release focuses on quality improvements and bug fixes, including a fix for the problem that prevented some users to have access to "internet connectivity on some cellular modems after upgrading to Windows 10, version 2004."
