Microsoft Edge first browser to get Windows 11 accelerated launch
Windows 11's October 2026 optional update KB5127936 adds accelerated app launch, giving Edge up to 33% faster starts when multitasking.
Microsoft's Windows 11 optional update for October 2026, KB5127936, adds support for accelerated app launch, making Microsoft Edge the first browser to use the feature, according to Windows Central. The update is available now as an optional non-security release.
With the feature, Edge launches about 15 percent faster in general use, and up to 33 percent faster when the system is multitasking heavily. The gains apply in the Start menu, the Taskbar, and supported links that open in Edge by default.
The improvement only appears after Edge has already been opened and is running in the background, because accelerated app launch requires both the app and Windows 11 to work together. The update also includes an updated context menu and Cloud Rebuild.
Microsoft is contributing its work on the feature to Chromium so other Chromium-based browsers can benefit, and it is also working on opening PDF files using the feature, Windows Central reported.
Why Edge came first
Microsoft made Edge the first app to ship accelerated app launch because Edge is the built-in browser on Windows 11, according to the report.
