The new Edge will not replace the default browser on those systems, although it can be set as the default once it is installed. When this patch is applied to an organization’s devices, Microsoft Edge Legacy will be removed from those machines and the new Microsoft Edge will be installed.

On April 13, also a scheduled Patch Tuesday, the new Microsoft Edge will be installed as part of that month’s cumulative updates. The browser will receive its final set of updates on that date, but after those are installed, the old version of Microsoft Edge Legacy will no longer receive routine or security-related updates. The official end-of-support date for Microsoft Edge Legacy is March 9, which coincides with the monthly Patch Tuesday update for that month. This month, Microsoft reminded customers of its sundown plans for Microsoft Edge Legacy. That replacement plan never came to fruition and now that browser, referred to as Microsoft Edge Legacy, has been replaced by the new Microsoft Edge browser based on Chromium. Shortly after Microsoft released Windows 10 in 2015, the company added its own new browser to the operating system, which was intended to coexist alongside Internet Explorer and eventually replace it as the de facto browser for Windows.
