As part of the first semi-annual update coming in 2020, Microsoft is now rolling out Windows 10 build 18841 for devices enrolled in the Fast ring with the Skip Ahead option. This is the second preview releasing to testers for the 20H1 development coming in spring 2020.

According to the company, build 18841 doesn’t introduces new features, only a set of fixes already available in the latest 19H1 builds.

While participants of the program with devices in the Skip Ahead lane are getting build 18841 today, Microsoft explains some features coming next year need a longer lead time. Once the April 2019 Update becomes available, testers will once again receive previews for the 19H2 development. 

Microsoft is listing the complete set of improvements, fixes, and known issues for Windows 10 Insider Preview build 18841 at the Windows Blog.
