Microsoft has started testing a new Windows 10 feature update 19H2 aka Version 1909 Build 18363.329 to the Release Preview ring. Microsoft, as we already know is making this build available to only a small set of Release Preview ring insiders. For other insiders in Release Preview Ring, 19H1 Build 18362.329 is rolling out.

The two builds bring same fixes. Check the full changelog below.

  • 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.

It seems that all future 19H1 and 19H2 builds will have common cumulative update with the same fixes.

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. As we continue to test our servicing packages in the Release Preview ring, Insiders on 19H1 and 19H2 will get a single Cumulative Update with the same fixes.
