Microsoft is currently developing the next Windows 10 update, codenamed 19H2, and scheduled for launch in September this year that focuses on bringing improvements and updates to the existing Windows 10 19H1 release available now. This is a first for Microsoft, dedicating a major feature update to improving an update that already exists. 19H2, when it’s ready, will sit on top of 19H1 just like a normal Windows 10 patch, meaning there’s less risk when updating, and less downtime when the update is installing.

This release will be delivered to users differently than previous Windows 10 feature updates, because 19H2 is just an update for 19H1, and not a full blown standalone release. Unlike normal Windows 10 feature updates that require large downloads and long reboot times to install, 19H2 will be delivered just like a normal Patch Tuesday update, known as a Cumulative Update. The download won’t be as large, and won’t take as long to install or restart.

What’s the difference between feature updates and cumulative updates?

The 19H2 release will have less new features than a normal Windows 10 feature update, but that’s by design. Microsoft is dedicating 19H2 to fixing bugs, improving performance, and introducing minor new features for enterprises and developers to take advantage of. With that in mind, there are still changes to be noted, and as with every new Windows 10 feature update, we’re going to compile every change into an easy to view list so you can keep track.

19H2 changelog (so far)

As Windows 10 19H2 is still in development, this changelog is considered incomplete. We will continue to update it with every new preview build that Microsoft rolls out up until public release.

  • Windows containers require matched host and container version. This restricts customers and limits Windows containers from supporting mixed-version container pod scenarios This update includes 5 fixes to address this and allow the host to run down-level containers on up-level for process (Argon) isolation.
  • A fix to allow OEMs to reduce the inking latency based on the hardware capabilities of their devices rather than being stuck with latency selected on typical hardware configuration by the OS.
  • Key-rolling or Key-rotation feature enables secure rolling of Recovery passwords on MDM managed AAD devices upon on demand request from in-tune/MDM tools or upon every time recovery password is used to unlock the BitLocker protected drive. This feature will help prevent accidental recovery password disclosure as part of manual BitLocker drive unlock by users.
  • A change to enable third-party digital assistants to voice activate above the Lock screen.

This changelog includes all the changes noted up to build 18362.10005.
