Microsoft quietly rips react out of windows 11’s start menu to make it feel alive

microsoft is gutting the web guts of Windows 11. The next insider drop will ship a Start menu no longer stitched together in JavaScript; the “Recommended” section and the app list are being re-forged in WinUI, the company’s native framework that talks straight to the GPU. The promise: less stutter, zero frame drops, and a menu that snaps open like a physical drawer.

The react romance cools

Two years ago microsoft swiped right on React. Web code let designers iterate at the speed of a refresh button, and Redmond pushed pixel-perfect tiles to the world in days, not months. The honeymoon ended when telemetry showed the menu taking 300 ms longer to paint on a cold boot than the rest of the shell—an eternity in human finger time. Engineers traced the lag to the JavaScript bridge that translates every click into a native call; it’s like shouting an order across a windy courtyard. WinUI short-circuits that chatter, painting pixels from the same metal the OS sleeps on.

Internal builds already show the delta: the new menu renders in 16 ms on a Surface Go 3, down from 52 ms. Gamers won’t care, but the secretary who opens Start 200 times a day will feel the difference in her wrist.

Rollout will be invisible—until it isn’t

microsoft won’t flip a giant switch. Instead, React islands will vanish patch by patch, starting with “Recommended.” By late 2025 the entire Start codebase is slated to compile down to native ARM and x64 instructions. Legacy machines get the same bits through cumulative updates, no reinstall required. The company is betting the gradual fade avoids the backlash that met Windows 8’s wholesale overhaul.

Users who hate algorithmic nudges can still kill “Recommended” from Settings; doing so also nukes recent files in Explorer and taskbar jump lists. The toggle lives exactly where it did before, but now the shell redraws itself without spawning a single Chromium thread.

microsoft’s larger agenda lurks beneath the Start button. Once WinUI digests the menu, the same engine will ingest the taskbar, the system tray, even the lock screen. The long game is an OS that feels like a single piece of glass instead of a Jenga tower of runtimes. If the experiment sticks, the last lingering trace of React inside Windows 11 will be the Edge browser—an irony not lost on the engineers who once celebrated shipping a web app inside every shell pixel.
