Microsoft has released a brand new build for Windows 10 insiders that allows them to check out the upcoming 19H2 update due in the fall.

As per Microsoft's new approach, Windows 10 19H1 builds are shipped included in cumulative updates via Windows Update, so today, Slow ring insiders are supplied with KB4508451.

This new cumulative update boosts the OS build number to 18362.10006, even though it doesn't include any changes, it will activate the features that were part of the previous release.

Gradual rollout of new features

Microsoft enables Windows 10 19H2 features in preview builds utilizing a gradual approach, so few are getting all the changes when a latest version rolls out. Instead, the organization says it's doing this at a slower pace to check reliability first, so if the testing goes as planned, more users would be receiving the new features.

"Today we have released 19H2 Build 18362.10006 for any subset of Windows Insiders that turns on the characteristics delivered included in Build 18362.10005 (noted in the below blog post) the 2009 week. Please be aware that Build 18362.10006 is just going out to a subset of Insiders within the Slow ring. That means not everybody in the Slow ring will get this update," Dona Sarkar, chief from the Windows Insider program, announced today.

The four features that this cumulative updates enables incorporate a change that allows third-party assistants to run above the lock screen and wait for voice input, in addition to a fix to permit OEMs reduce latency for inking on their own devices.

Windows containers require matched host and container version, while a separate new feature may prevent accidental recovery password disclosure during manual BitLocker drive unlocking.

Windows 10 19H2 is supposed to be finalized in September after which released to production devices a month later, according to Microsoft's typical release schedule.
