Microsoft announced today that Windows 10 version 20H2 is ready for commercial validation, one of the final milestones in the schedule for this decidedly minor upgrade.

“Windows 10 version 20H2 is now available for commercial customers to begin feature exploration and validation prior to being released for general availability,” Microsoft’s Aria Carley wrote. “You can access Windows 10 version 20H2 through all standard outlets, including Windows Update, Windows Server Update Services (WSUS), and Azure Marketplace, or you can download an ISO file.”

Like Windows 10 version 1909, Windows 10 version 20H2 is not a real feature update if you’re upgrading from version 1903. In that case, it is just another cumulative update, similar to the updates we all install every month. (For those upgrading from versions of Windows 10 version 1903, Windows 10 version 20H2 will install like a normal feature update.) That means it will install very quickly, though it does require a reboot.

“As with Windows 10 versions 1903 and 1909, versions 2004 and 20H2 share a common core operating system with an identical set of system files,” Carley continues. “New features are included in monthly quality updates for version 2004 in an inactive and dormant state. These new 20H2 features remain dormant until they are turned on through the ‘enablement package,’ a small, quick-to-install ‘master switch’ that activates the Windows 10, version 20H2 features.”

The enablement package she refers to was apparently added to Windows 10 version 2004 with the June 2020 monthly quality update. So organizations running managed, commercial versions of Windows 10—e.g. Windows 10 Pro or better—can now flip the switch and check out the handful of new features.
