Microsoft has just rolled out a new cumulative update, KB4552455 for Windows 10 Version 2004 in the slow ring channel. This cumulative update only fixes certain shortcut key issues. However, Windows 10 Version 2004 has not yet been officially launched, so all cumulative updates are beta.
At the same time, this update only fixes the Win + J shortcut key may not work properly, so for most users, it doesn’t matter whether to install this update.
After successfully installing this update, the system version is upgraded to Windows 10 Version 2004 (20H1 Build 19041.172), which is not a security update.
A known issue with this update is that the Narrator and NVDA users may have compatibility issues with Microsoft Edge.
At present, the NVDA project team has launched a new version, NADA 2019.03, to fix this problem. Users who need it can click here to download the latest version.
