Windows 10 May 2020 Update (also known as version 2004 or 20H1) is an update for Windows 10 which was released on 27 May 2020. This version is notable for having the first Insider Preview builds released before Windows 10 November 2019 Update, which it has replaced. It is the last Windows 10 feature update to use the former YYMM scheme for the version number which had been in use since Windows 10 November Update as Microsoft started to use the YYHx scheme for future updates starting with Windows 10 October 2020 Update. It is also the last Windows 10 feature update to add any notable major new features as later Windows 10 feature updates were minor updates that mostly added features for enterprises and focused on bug fixes and security updates as Microsoft shifted future major feature development to Windows 11.
After its release, Microsoft released a number of new builds to the Dev Channel (formerly the Fast ring) that were not tied to any particular Windows 10 release, while the Beta Channel (formerly the Slow ring) received builds of the Vibranium-based October 2020 and May 2021 updates and the Release Preview Channel received updates to this version.
