Microsoft has released first Windows 10 19H2 preview build, the next feature update after the Windows 10 May 2019 or version 1903 update to insiders. Microsoft has however tweaked the way in which 19H2 will be tested by insiders.
Only insiders that are running Windows 10 May 2019 update and are enrolled to the Slow ring will get this build as a cumulative update. Here are the details from the official blog post.
- Insiders will need to be in the Slow ring and on the May 2019 Update to receive 19H2 bits.
- 19H2 will be delivered to Insiders in the Slow ring via servicing as a Cumulative Update and not full build updates.
- Some Insiders may not see the new features right away as we perform controlled feature rollouts (CFRs) to gain better feedback on overall build quality.
- Specific to CFRs, we may ship features in these updates turned off by default and turn them on independently of bits getting downloaded to Insiders’ PCs.
Coming to what is supposed to change with this Build 18362.10000, here is again the official bit from blog post. There are two changes invisible to insiders. Also, these updates will have some improvements and fixes as the latest May 2019 cumulative update plus 19H2 changes.
This update contains two behind-the-scenes changes designed for OEMs and does not contain anything visible to Insiders. We’re using this update to test our process and servicing pipeline for delivering these updates to customers. 19H2 updates to Insiders will also be cumulative with the latest May 2019 Updates. For example, today’s release also includes the same improvements and fixes contained in this Cumulative Update released for the May 2019 Update here. Going forward, these updates will continue to contain the same improvements and fixes released for the May 2019 Update in addition to new 19H2 changes.
