The Windows 10 May 2020 feature update will be available from May 26-28, while the next feature update version 2009 will focus more on BUG fixes, background performance optimization, and other general adjustments.
In the latest Build 19041.264 preview update, it has been listed as Windows 10 20H2 in the registry entry. In addition, this version includes an “enablement package” that enables Version 2004 to be version 2009.
Windows 10 Version 2004 and Version 2009 will share the same system files, and the new features of Version 2009 (20H2) will be included in version 2004 monthly updates, but the features will be in a “sleep/disabled state.” Version 2009’s Windows 10 features are built on Windows 10 Version 2004, but they are set to Disabled before you install the enablepack.
In September or October, Microsoft will release a quick-installed Master Switch that will activate the enable pack to enable Windows 10 Verison 2009. The company will use “service technology” to deliver the 20H2 update, which will minimize the possible disruption caused by the feature update.
