Windows 11 has introduced an "accelerated app launch" feature, initially benefiting Microsoft Edge. This feature allows Windows to open Edge more quickly by routing requests directly to the existing instance of the app instead of starting a new temporary process. The update, KB5127936, was rolled out to Windows Insiders on October 16, 2026, and is part of updates for Windows 11 25H2 and 26H2. The enhancement primarily improves the launch speed of Edge when it is already running in the background, particularly benefiting warm launches. Testing showed that Edge launched faster when other applications were active post-update. Microsoft aims to extend this feature to other single-instance applications, but it requires developers to meet specific prerequisites and request access to certain APIs. The accelerated launch feature is expected to be available as an optional update around November 10, 2026.
