Adblockers are coming to Microsoft Edge. Edge is the new default web browser in Windows 10, the successor to Internet Explorer. IE 11 is still there in Windows 10, but it's kept in a small room in the back out of the way, with the curtains drawn and the door closed, if not actually locked.
When Windows 10 launched, Edge has essentially no plugins although we are now starting to see them slowly emerge (as promised by Microsoft). Adblock and Adblock Plus are not generally available yet, but are showing up in the Windows Store for users running so-called "Insider" versions of Windows 10 - cutting edge previews of things to come.
