Microsoft released a new update for the latest version of the company’s Windows 10 operating system, Windows 10 version 2004. KB4568831 for Windows 10 version 2004 and Windows Server version 2004 is a non-security update that fixes several bugs found in earlier versions of the operating system.
The update is available via Windows Update and also as a direct download from the Microsoft Update Catalog website. On Windows Update, it is necessary to check the “optional updates available” section under Settings > Update & Security > Windows Update; the update should be listed there.
The new update is a preview update and as such, should not be installed on most devices. It may make sense to install the update if you experience at least one of the issues. In all cases, it is advised to back up the system before the update is installed.
