https://arstechnica.com/gadgets/2021/07/early-windows-11-builds-show-microsoft-has-lots-of-work-ahead/ > Microsoft made early Windows 11 builds available via its Windows Insider program the week after its first major announcement, and we've spent quite a few hours kicking the tires. When Windows 11 publicly releases, it's likely to be a fine operating system—but right now, it's an unpolished, unfinished mess. > Of course, this isn't a surprise—Windows 11 is still only available in the Dev channel of the Insider program. The three Insider channels are Release Preview, Beta, and Dev; Dev roughly corresponds to a software alpha, and Microsoft itself describes it as "the newest code," with "rough edges and some instability."
