Microsoft just announced pausing all optional, non-security Windows 10 updates starting in May, 2020 due to the current public health situation. This means the Windows maker will now stop working on optional updates. Before today's announcement, Microsoft released optional Windows 10 cumulative updates for versions 1903 and 1909. These updates were already delivered to the older versions of the operating system last week.

KB4541335 is now out for Windows 10 May 2019 Update (Build 18362.752) and the November 2019 Update (Build 18363.752). Today's Windows 10 cumulative update brings fixes to the printing issues, the problem with the mute button while using Your Phone app, bug that prevents some apps from closing, calendar, and some keyboard issues.
