Although it supports Windows 8 and IE10 in desktop mode, it couldn’t reach the 1.0 version in years, and has some serious limitations.

Because IE is bound to the underlying OS you cannot install multiple IE versions side by side (which can be done with some other browsers), so you need other solutions. Testing a website with multiple Internet Explorer versions can be frustrating.
