Windows 11 is getting "accelerated app launches," and I tested it on a PC with just 4GB RAM. Surprisingly, Microsoft Edge now opens much faster when other apps are already running, and Microsoft says this feature will eventually be available to other Windows apps, too! Previously, when Edge was already running in the background and you opened it from the taskbar, Start menu, or a link, Windows would create an extra, temporary process just to tell the existing Edge instance to open. The process would then exit. With the new accelerated launch feature, Windows skips that unnecessary process and sends the request directly to the running instance of Edge. I tested it before and after installing KB5127936 on a Windows 11 virtual machine with a paltry 4GB RAM. Before the update, Edge opened fairly quickly when the PC wasn't doing much, but there was a noticeable delay when Store and Paint were open. After the update, Edge opened surprisingly faster under the same conditions. To be clear, this only improves warm launches, where the app is already running in the background. Opening Edge for the first time after a restart won't benefit from this feature. This feature will also come to other apps, as Windows 11 keeps getting better!
