Microsoft says a Windows 11 change can make Edge open up to 33% faster when the browser is already running in the background. Most people should see around 15%, and the gain shows up mainly when your PC is busy with other work.
The speed-up does not help the first start after a reboot. It applies when you click a link or open Edge from the Start menu or taskbar while an Edge process already exists, which is common because Edge often stays alive through its Startup Boost feature.
Until now, Windows launched a short-lived helper process every time you opened Edge, to check whether a copy was already running and pass the request along. Under the new scheme, described in Microsoft’s Edge blog post, a running Edge registers itself with Windows, which then hands later launch requests straight to it and skips the helper. Microsoft calls it Accelerated App Launch.
You need Windows 11 version 25H2, 26H1 or 26H2 with the optional update KB5127936 from 28 October or something newer, plus Edge 150 or later. Nothing has to be switched on by hand. Microsoft is rolling it out gradually, so installing the update does not guarantee you have it yet. Wccftech’s write-up points out that the figures describe warm launches only, so they are not a blanket speed boost for Windows.
The warm-start limit is worth keeping in mind when reading the numbers. Microsoft’s 15% is what it expects most users to see, and the 33% is the best case under heavy multitasking, measured against Edge launching without the feature while it already runs in the background. A cold start, when no Edge process exists, is unchanged.
Edge is the first app to use it, but the plumbing is meant for others. Microsoft’s documentation lets single-instance Windows apps register for direct launch requests, though the interface is a Limited Access Feature for now, which means developers have to ask Microsoft for access. Microsoft is also contributing the work to Chromium, so Chrome, Brave and Vivaldi could get the same shortcut later, and it is looking at faster handling of PDF files opened in Edge.
Microsoft’s post says the faster path is used for launches from the Start menu, from the taskbar, and from links in other apps that Windows sends to Edge. Microsoft’s reasoning is that Edge is usually alive already, whether through a visible window or a background session, so the lookup step was wasted work on most launches. On a lightly loaded PC that work costs little, which is why the gain is smaller there and grows when many programs compete for the processor.
