14 DAY TRIAL // Microsoft has shipped a new cumulative update for Windows insiders currently enrolled in the Release Preview ring and testing Windows 10 19H1 and Windows 10 19H2 releases.
Because Windows 10 19H1, also known as version 1903 and May 2019 Update, and Windows 10 19H2, referred to as version 1909 and November 2019 Update, share the same servicing content, they get the same cumulative updates as well.
The update that Microsoft released today to the Release Preview ring is KB4522355, and it is thus available for both those who run 19H1 and 19H2 builds. This cumulative update comes alongside a new servicing stack update labeled as KB4525419.
A changelog for this new cumulative update isn’t yet available, but after installation it increases the OS build number to 18362.446 on Windows 10 19H1 builds and to 18363.446 on Windows 10 19H2.
Coming later this month for production devices
Most likely, the same cumulative update will also be released later this month to production devices running Windows 10 May 2019 Update (version 1903). The software giant published a new batch of cumulative updates for Windows 10 on October 15, but version 1903 wasn’t part of the rollout.
At the same time, this pack of improvements will also be included in the final build of Windows 10 November 2019 Update (version 1909) when it launches next month.
Windows 10 version 1909 itself lands as a cumulative update, so it includes all the previously-released fixes as well. According to a recent leak, this Windows 10 feature update is projected to land on November 12 for the first wave of devices. November 12 also marks the next Patch Tuesday cycle when Microsoft will publish new cumulative updates for all Windows 10 versions.
We’re still waiting for a changelog for cumulative update KB4522355, but as it happens every time, we’re unlikely to get one until the same update becomes available for production devices.
