Update 22 Well Microsoft has released a separate version that runs on Windows 7 and 8. Now you can just download and install it like any other program. Im keeping the original answer below You don't. It's simply impossible . Microsoft Edge is built entirely on the Universal App platform which was introduced in Windows 1. The platform is based on Windows 8's Windows Store platform formerly known as Metro so theorically it could be possible to port it to Windows 8 but you could only run it in full-screen mode just like every Windows Store app in Windows 8. However the Windows Store platform was created from scratch and had nothing to do with Wi2 framework which is used in previous versions of Windows. That makes it impossible to port such applications to previous versions without eitherpletely re-programming the whole interface (which would basically result in the same Internet Explorer that you already have) or porting the whole Universal App platform to Windows 7 - which would take a whole Microsoft team and several months worth of work.
