The Chromium-based Edge stable version can be downloaded from the Microsoft server in the Google search engine. At present, the stable version of Edge has been leaked in advance, and interested users can download the installation file signed by Microsoft from the Microsoft server. It should be noted that once the user is installed on a Windows 10 device, Chromium Microsoft Edge will completely replace the classic Edge browser, and will not coexist with the Edge browsers.
Clicking the first result on Google begins the download of the supposed stable build of Microsoft Edge. The app downloads and installs correctly, and the version of the browser is 78.0.276.19. Everything seems to be running correctly, and checking for updates also appears to be working fine, with no error whatsoever. The stable version is based on Chromium 78.0.3904.63.
