When Microsoft first announced general availability of its new Chromium-based Edge browser, it said that those on Windows 7 and 8.1 would have to install the browser manually if they wanted it. As it turns out, Microsoft is pushing it out over Windows Update anyway, according to a KB article
published this week. There are a few key things that you need to know when you install this. First of all, it's going to add Edge to your taskbar and as a desktop shortcut. Also, it's not going to replace Internet Explorer like it replaces Edge Legacy on Windows 10. And finally, it won't change your default browser.
This is a particularly interesting change for Windows 7 users, because the OS hasn't been supported since January. The only users that are supposed to get updates are those paying for Extended Security Updates; however, it seems that Microsoft is willing to pick up Edge users wherever it can.
