Microsoft ships Edge with Windows 10, the successor to its browser, Internet Explorer (although IE is still present in the OS). However, for many individuals, using Chrome or Firefox, no matter what Microsoft wants, is the norm.
Open Edge, search for either and find a Windows 10 version to install Chrome or Firefox-and get back to normal. Download it, install it, and make sure that Edge doesn't reappear as the default browser option. To do this, go to Settings, System, and click Default Apps. You can select your desired default browser by clicking on the Web browser.
But, you may have less reason to switch over now that Microsoft Edge is moving to Chromium.
