Like before, Microsoft released a test update to insiders in the Dev channel.
This time it’s KB5004071 to test the servicing pipeline, according to Microsoft. If you like to install the update anyway, you can get it down below.
Microsoft: UPDATE 6/7 We are starting to roll out Cumulative Update Build 21390.1000 (KB5004071). This update does not include anything new and is designed to test our servicing pipeline.
We have been testing our servicing pipeline with Cumulative Updates to the builds released to the Dev Channel. Each week, we would release a new build and then follow up with a Cumulative Update on top of that build before moving to the next build. However, we need to test the process of releasing multiple Cumulative Updates on top of each other on top of the same build. As a result of this, over the course of the next several weeks, our focus will be on releasing multiple Cumulative Updates on top of Build 21390. Having Insiders in the Dev Channel test will be immensely helpful, and we’ll be back to flighting normally again soon!
