Ahead of March’s Patch Tuesday releases, Microsoft has released a preview of the KB4601382 update. This cumulative update is available for Windows 10 2004 (Windows 10 May 2020 Update) and Windows 10 20H2 (Windows 10 October 2020 Update), and it includes a number of important fixes.
Some of the highlights of this particular update include addressing a screen flicker issue during video playback, fixing a problem that prevented some keyboard keys from working, and improving application startup times in certain scenarios.
KB4601382 is a non-security update, but this does not mean that it is any less significant. The update takes Windows 10 2004 up to build number 19041.844, and 20H2 up to 19042.844.
