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.[1] 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 after the May 2020 Update have been 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 recieved updates to this version.

New features and changes[edit | edit source]

  • Most references of "PC" have been replaced with "device", such as in the message when a bugcheck appears. This is because "device" also targets to non-PC devices such as laptops or tablets.
  • A new option to restore the device over the cloud (this means the system downloads the restore image from the internet) has been added as an alternative to the now-called local restore.
  • Windows Subsystem for Linux has been updated to version 2. This version uses an actual Linux kernel rather translating Linux to Windows NT commands. It was later ported back to Windows 10 May 2019 Update and Windows 10 November 2019 Update.
