The naming nightmare is over. Microsoft, the company that brought you names like Windows RT 8.1 and Windows Phone 7 Series, finally has a single name for its core Windows products: Windows 10. That’s right. The next version of its operating system will be called Windows 10 whether it’s running on a phone, a tablet, a laptop, or a desktop PC. That’s a particularly sensible decision this time around. Microsoft has been making a big deal about the ability for “universal” apps to run across different form factors — from phones to the desktop — so branding it all as the same system should help consumers understand that it’s meant to be a consistent platform.
