Microsoft has released two builds from the upcoming Windows 10 19H2. Build 18362.10012 will be available for those who are currently running Windows 10 19H2 Build 18362.10005; Build 18362.10013 is out for Windows Insiders currently on 19H2 Build 18362.10006. Both builds are now out for Slow ring Insiders.

As the Windows maker had announced earlier, it is testing the ability to ship new updates with features turned off by default so that they can be turned on via controlled feature rollouts. “This helps us gain better feedback on overall build quality,” Microsoft writes. “A subset of Insiders in the Slow ring will have features turned off by default, and another subset will have them turned on by default.”
