Windows 11 build 21343

Windows 11 build 21343 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 build is one out of three known builds to be compiled from a branch with the  prefix, the other two being builds 21327 and 21380. The prefix stands for Firesteel, the codename for an internal Microsoft tool related to Windows 11 development. This build also has an earlier version of the new Start button, as the Windows logo is the inverted colour of the taskbar, instead of a blue gradient. Rounded corners on windows and centered taskbar buttons are also present. In addiiton, various icons have been redesigned.
