This is an escalation in the war between Edge, Chrome, and Firefox. There is also an option to disable the warning type in the future but that leads to the Apps listing of the Settings application and no option to do anything about that.
"Dropbox or Google Drive are outdated thanks to the great OneDrive feature in Windows 10". It's particularly bold for Microsoft to surface this pop-up as soon as you try to launch the installer for another browser as well, and we can't really see its existence sitting well with the larger Windows 10 userbase. The idea seems to be to interrupt the install process for third-party browsers in an effort to drive adoption of Edge as the default browser. This is normally set to the default option of "install apps from anywhere", but when the Windows 10 Update arrives in October, it will be changed to "show me app recommendations". There is a button that allows users to open the Edge browser instead of installing Firefox or Chrome. The popup notes that users already have Edge as part of Windows 10, and claims that it is the safer and faster browser. Now, Redmond appears to be at it again, after a Windows 10 pop-up test was discovered that advised users to choose Edge over other browsers.
That said Edge's score is only slightly lower than the others, and while it's missing some features, such as support for the 3D graphics rendering API WebGL 2, it supports some features missing from Chrome, such as the WebVR API for using virtual-reality headsets in the browser. This is no way to encourage more users to start using Edge. How do you get those people to give Edge a chance?
Typhoon Mangkhut: millions in path of storm and monsoon rains
Typhoon Haiyan left more than 7,300 people dead or missing and displaced more than 5 million in the central Philippines in 2013. The Pearl River Delta region, which includes Hong Kong and Macau, is among the most densely populated in the world.
Even more frustrating is the fact that Windows displays this prompt even when you're installing yet another browser.
Here's the amusing thing: Despite all these tricks, Edge only has about 4% of the browser market.
People talk about how Google pushes Chrome, but that's pretty different. Microsoft stated in 2017 that Edge usage had doubled but third-party usage tracking service still see the browser lag behind Chrome, Firefox and even Internet Explorer in usage share. So maybe you should make Edge a better browser instead of thinking up new ways to shove it in our faces.
