Microsoft is releasing a new Windows 10 19H2 build today. Well, kind of.

Here’s the thing: Microsoft is testing a new controlled feature rollout (CFR) system in Windows 10 19H2 that involves the company introducing new features that are initially only available to a subset of Insiders, and are later made available for everyone else.

The company released build 18362.10005 to Insiders in the Slow Ring on Monday with a couple of new features and changes. But none of those features was actually turned on because Microsoft was using the build to test the new CFR system.

Today, it’s releasing build 18362.10006 to turn those features on. Here’s what’s new:

• 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.

And if that wasn’t confusing enough already, Microsoft says the latest build — 18362.10006 — is only available to a subset of Insiders in the Slow Ring, that means not everyone in the Slow Ring will actually get this new build. That’s the new CFR system in action for you.
