StatCounter’s global stats, puts Windows 10 adoption rates to about 5.34%, just after one week of the release, comparing Windows 7 which only reached 4.05 percent usage after its debut six years ago, and Windows 8 only achieved 1 percent of usage.
Now, how does Windows 10 adoption impact Microsoft's newest browser, Edge? If you had set Firefox or Chrome as your default Web browser in Windows 7, 8, or 8.1 upgrading to Windows 10 will automatically reset it to Edge.
And given the technical tussle required for people to reset their browser, introduced by Microsoft in Windows 10, now taking more than twice the number of clicks, while scrolling through hidden settings. So many people find it difficult to reassert the choices they had previously made in earlier versions of Windows.
Albeit, when a user upgrade from Windows 7, 8 or 8.1 to Windows 10 with "express settings" selected, it does indeed reset all default apps and their file associations, but requires a bit more effort to set new default apps.
Still, StatCounter notes that usage of Microsoft’s new Edge browser has steadily decreased since late July, and perhaps, many users haven’t really hit the “make default” button on Windows 10 to Edge, keeping in their old comfort zone usually with Chrome or Firefox.
