Microsoft Edge 83 is another major feature update for the Chromium-based browser on Windows 10, Windows 7, Windows 8 & 8.1, and Windows 10 versions of Microsoft Edge. The update is rolling out in a phased manner, as opposed to a quicker and wider release. Microsoft is introducing automatic multiple profiles switching feature, which aims to automatically choose your work profile when you navigate to a site requiring authentication from work or school account when you are on your personal profile. The feature needs to be enabled from the settings screen after updating the browser.
