What you need to know
- Windows 10 Insiders on the Release Preview ring have a new cumulative update to download.
- There are two different build numbers depending on whether you've been selected to test the 19H2 update or are still on 19H1.
- The cumulative updates contain the same set of two fixes related to LTE connectivity and bugchecks.
Following up on a new build for Fast ring Insiders today, Microsoft also pushed out a pair of new cumulative updates for Windows 10 Insiders on the Release Preview ring. The new build numbers are 18362.329 and 18363.329, which are available to testers on the 19H1 and 19H2 updates, respectively.
Both updates contain the same set of fixes, which address LTE connectivity and bugchecks. Here's a look at the release notes:
- We fixed an issue where on devices with LTE capability, some SIM cards from certain carriers would not work correctly.
- We fixed several issues resulting in bugchecks on some devices.
The reason for the somewhat confusing update structure and dual builds is that Microsoft is currently testing its servicing pipeline for the upcoming 19H2 feature update with a small subset of Release Preview Insiders (around ten percent). As part of today's release notes, Microsoft explained how it is treating build numbers for each branch of Release Preview, noting that they will differ on build numbers but always share the same revision numbers. From Microsoft:
To offer a clarification on these releases – 19H1 and 19H2 share the same servicing content. That means they share the same Cumulative Update package. For the small subset of Windows Insiders (the 10%) in Release Preview who were given the option to install 19H2, an enablement package is downloaded from Windows Update that turns on the 19H2 features. This changes the build number for the OS from 19H1 Build 18362 to 19H2 Build 18363. Because they use the same servicing content, the build revision number (the number that comes after the dot) will always match between 19H1 and 19H2.
Going forward, cumulative updates released to both sets of testers will include the same set of fixes..
