Microsoft Rebuilding Windows 11 Start Menu on WinUI 3 for Speed and Customization

The move signals a renewed focus on performance under Microsoft's Windows K2 effort.

Overview

  • Multiple outlets report Microsoft is rebuilding the Start menu on WinUI 3, which the company has said is in the works according to Windows Central.
  • Users would be able to pick a small or large layout instead of having Windows choose based on screen size.
  • New switches in Settings would let people hide whole sections such as the Recommended feed, the pinned apps area, or even the All apps list.
  • The team is aiming for instant response even under heavy CPU load, including faster search that stops missed keystrokes.
  • The company has not given a release date, with reports suggesting the update could land sometime in 2026.
