A tiny helper application to force Windows 10 to use your preferred web browser instead of ignoring the setting to promote Microsoft Edge. Only runs for a microsecond when needed. - da2x/EdgeDeflectorgithub.com
Have you updated you PC with the latest windows updates. If so, it should have updated Edge to the new Edge Chromium. IF not, you can download it separately from here. It's so customizable now and very easy to use just like Chrome.
