Microsoft has released a new build for Windows 10 insiders in the Beta channel, obviously as part of a new cumulative update that is specifically supposed to further refine the experience ahead of the 21H1 update due later this spring.

Windows 10 cumulative update KB5000842 increases the OS build number to 19043.899, and according to the official changelog, which you can check out in full in the box after the jump, the focus has been specifically on improving the overall performance of the OS and resolving some of the bugs in there.

For example, there are fixes aimed at File Explorer, Microsoft Edge, and touchpads, as well as improvements that prevent the explorer.exe from experiencing a heap leak that eventually causes high memory usage.

Windows 21H1 coming in the spring

According to Microsoft’s typical release calendar, Windows 10 21H1 is projected to be finalized in the spring before being pushed to the production devices in April or May.

Windows 10 21H1 will land as a minor update with the focus on under-the-hood improvements and less on new features, thus becoming the second update in a row to be shipped as a quality release.

“Based on feedback and learnings during the past year of extensive remote work, learning and play, version 21H1 will be delivered with servicing technology (like that used for the monthly update process and how 20H2 was delivered).  Windows 10, version 21H1 will have a scoped set of features improving security, remote access and quality. The features we are releasing in this update are focused on the core experiences that customers have told us they’re relying on most right now. So, we optimized this release to support our customers’ most pressing needs,” Microsoft said recently.

You can try out Windows 10 21H1 early by enrolling in the Beta channel of the Insider program.
