Changes[edit | edit source]

User interface[edit | edit source]

This build introduces an updated File Explorer icon, which matches Microsoft's Fluent Design language.
The OOBE icons from Windows 10X and build 21370 have been updated.
Some UI fonts have been replaced by Segoe UI Variable.
The start button icon has been updated.
The taskbar hover animations from 21370 have been removed.

Branding[edit | edit source]

The system now generally identifies itself as Windows 11. Although this is moot, as system still identifies itself as Windows 10 in Registry Editor, by navigating to HKLM\Software\Microsoft\Windows NT\CurrentVersion, in Control Panel's legacy System applet, and NT version remains practically same as in Windows 10.
The boot screen logo was changed to the final version.
