Microsoft is working to improve the Edge browser, which is the default browser in Windows 10 instead of Internet Explorer. Microsoft is trying to make it more useful for the end user. With every major update for Windows 10, it is getting more features. Windows 10 Anniversary Update, which was formerly known as "Redstone" will bring to Edge not only extensions support but also the ability to have more control over Flash animations.
During Build 2015, Microsoft made an announcement that Project Spartan which replaced Internet Explorer in Windows 10 is officially named Microsoft Edge. It is a WinRT-based browser. In the initial release, it won't support extensions or add-ons. So there can be no adblock extension or other tool to block ads in Edge for a while. Here is a trick which will allow you to block ads in the Microsoft Edge browser.
