What’s New in Windows 10 Cumulative Update KB4565503
It’s Patch Tuesday, and naturally, Microsoft has released a new set of cumulative updates for all Windows 10 versions, including the recently released May 2020 Update (version 2004).
Since the rollout of this feature update is still underway, only devices where version 2004 is already installed are getting Windows 10 cumulative update KB4565503.
The OS build after installing cumulative update KB4565503 is 19041.388 – you can check it by clicking the Start menu and then typing winver.
The first thing you need to know about this cumulative update is that it’s focused on security improvements, but this is something that was rather expected since it lands on a Patch Tuesday. However, it also comprises additional non-security improvements, including for the experience with games and applications that previously encountered a visual distortion when resizing in windows mode.
