After feeling the heat from macOS and Linux, Microsoft is getting its act together and making significant changes to Windows 11 to fix its biggest issues.

Buried in this announcement about Windows 11 improvements is a fascinating admission: the Windows 11 Start menu has been built using React this entire time. Microsoft is now migrating it to their native WinUI3 framework to improve performance and reduce interaction latency.

This explains a lot about why the Start menu has felt sluggish compared to Windows 10.

The React → WinUI migration is the most technically interesting detail imo.
