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). Scroll down to the bottom of the page and select the latest Beta Channel or Release Preview Channel edition, followed by the language (make sure the language matches your existing installation, or the setup will run into trouble later).UPDATE 6/14: We are starting to roll out Cumulative Update Build 21390.2025 (KB5004123).

That means important files, photos, music, games-anything you do not want to lose during the reinstallation. Before commencing with the reinstallation, you must backup your data. However, it is always a good idea to take a backup before making any major changes to your system. The result is a much faster upgrade with minimal data loss. Plus, you can use the in-place upgrade option, which means you don't have to wipe your system in the process. This method ensures you remain on the Beta Channel. If you don't want to switch Insider Preview paths, you can download and install the latest Insider Preview Beta Channel build. Reinstall Windows with an Insider Preview Beta Channel ISO
