While I agree with all of the above, I can't see how you've managed to end up with Edge on a Windows 7 machine!
Edge is the latest browser from Microsoft (which is intended to replace the dreaded Internet Explorer). It comes built into Windows 10 but it can't be downloaded or used with Windows 7. So the icon that you're seeing most definitely shouldn't be there!
That makes me consider the possibility that there could be some malware on your machine, which is trying to trick you into clicking on that suspicious icon and actually opening something nasty (instead of Edge).
So it might be best to run a malware scan. Download and run AdwCleaner. (There's no installation process involved; you simply run the downloaded file directly). If it reports finding something nasty, accept the option to zap it:
