Microsoft Edge opens faster on Windows 11 with Accelerated App Launch (KB5127936)
Microsoft Edge is the first browser to support Accelerated App Launch on Windows. With Edge 150+ and Windows 11 25H2/26H1/26H2 plus KB5127936 or later, most users get about 15% faster warm launches, and up to about 33% under heavy multitasking. The feature notifies an already-running Edge process directly instead of using an intermediary search step; it does not speed a cold start when Edge is not running.
