Need windows 11 beta Channel OS

Windows 11 hasn't yet (at the time of this post) been released to Beta Channel. It's still in Dev builds. If you join Beta Channel, you'll have to wait into Windows 11 arrives to Beta Channel which I heard will be sometime this summer. Windows 10 21H2 has been released to the Release Preview Channel which I believe is the channel where the Windows 10 preview/insider preview builds or updates will be going at this point. I believe Dev and Beta are currently reserved for Windows 11. Windows 10 builds will stay in the Release Preview Channel. If you go to this link, the part "Preparing the Beta Channel for Insider Preview builds of Windows 11" will give you more details about it. https://blogs.windows.com/windows-insider/2021/06/24/preparing-for-insider-preview-builds-of-windows-11/

Attached is a picture from one of my computers, and it matches to the link I posted above. Dev and Beta will be Windows 11. Release Preview Channel will be Windows 10. At least, for now anyhow hehe.
