Windows 11 Update Makes Microsoft Edge Launch Up to 33% Faster, With More Apps Set to Benefit

Windows 11 users who frequently switch between applications while working may soon notice a welcome improvement in everyday performance. Microsoft has introduced a new optimization designed to make applications launch faster, particularly when a computer is already handling multiple tasks. The technology, called Accelerated App Launch, is initially available for Microsoft Edge and can improve certain launch scenarios by up to 33%.

The improvement arrives as part of Microsoft’s ongoing efforts to make Windows 11 feel more responsive without requiring users to upgrade their hardware. Although the change may appear relatively small, it addresses an underlying process that can affect how quickly applications respond during busy computing sessions.

Microsoft introduced Accelerated App Launch through the optional October 28 KB5127936 cumulative update for Windows 11 versions 25H2 and 26H2, with support also extending to version 26H1. Microsoft Edge is currently the first application to benefit from the technology, beginning with version 150.

The optimization focuses on how Windows handles requests to open an application that is already running.

Previously, when users launched Edge through the Start menu, taskbar, or a supported hyperlink, Windows created a temporary intermediary process. That process checked whether an existing browser session was available. If Edge was already running, the temporary process forwarded the request to the active browser instance before closing.

While this approach generally worked without noticeable delays on lightly loaded systems, creating additional processes could introduce unnecessary overhead when several applications were running simultaneously.

Accelerated App Launch changes that process. Instead of creating an intermediary process for every launch request, supported applications can register their running instances directly with Windows. The operating system can then forward new requests to those instances without following the traditional process-redirection procedure.

According to Microsoft, this can deliver a more noticeable improvement when a computer is under heavy multitasking workloads. The company reports that Edge can launch up to 33% faster in certain scenarios, while a more typical improvement for users is around 15%.

However, there is an important distinction behind these figures. The performance gains apply to warm launches, meaning Edge must already have an active process. This could be an existing browser session or a background process maintained through a feature such as Startup Boost. Consequently, users should not expect every fresh browser launch or application startup to become 33% faster.

Microsoft is also looking beyond its own browser. The company has published technical documentation explaining how developers can adopt the underlying mechanism for other single-instance Windows applications. However, the associated APIs are currently classified as a Limited Access Feature, so developers must request access before using them.

There is also encouraging news for users of alternative browsers. Microsoft has confirmed that it is contributing the relevant technology to the Chromium project. This could eventually allow browsers such as Google Chrome, Brave, and Vivaldi to benefit from similar improvements. The company is also exploring faster PDF handling within Edge.

For now, users need Windows 11 version 25H2, 26H1, or 26H2 with the applicable October 2026 update or later, alongside Microsoft Edge version 150 or newer. Supported installations do not require manual activation.

There are still limitations, particularly because the optimization does not improve every application or guarantee faster cold starts. Nevertheless, reducing unnecessary background processing is a practical step toward a more responsive operating system. If Microsoft successfully expands support to more applications and browsers, this relatively modest update could become a meaningful improvement to the everyday Windows 11 experience.
