Windows 11 build 21390

Windows 11 build 21390 is a build of Windows 11. Footage of this build can be seen in the portfolio of the product motion design lead on Windows at Microsoft, Albert Yih.

This is the last build of Windows 11 to have its build range in the 213xx range, as the next build, build 21990, marks the jump from the 213xx range to the 219xx range, and it is also presumably the last build that has the Windows 10 background wallpapers.
