Hello Windows Insiders, today we are releasing Windows 10 Insider Preview Build 21390 to Windows Insiders in the Dev Channel. This update DOES NOT include any fixes for the known issues listed below. Having Insiders in the Dev Channel test this will be immensely helpful, and we’ll be back to flighting normally again soon! 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. However, we need to test the process of releasing multiple Cumulative Updates on top of each other on top of the same build. 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. We have been testing our servicing pipeline with Cumulative Updates to the builds released to the Dev Channel. This update does not include anything new and is designed to test our servicing pipeline.

UPDATE 6/7: We are starting to roll out Cumulative Update Build 21390.1000 (KB5004071).

UPDATE 6/10: We are starting to roll out Cumulative Update Build 21390.1010 (KB5004092). UPDATE 6/14: We are starting to roll out Cumulative Update Build 21390.2025 (KB5004123).
