The Windows 10 version 2004 Feature Update is expected to be released in the Spring of 2020 and it comes with a long list of improvements and new features.

Unlike the November 2019 Update, which was more like a service pack, Windows 10 2004 aims to bring new features and enhancements not seen in previous versions of Windows.
