A new Windows release wouldn't be the same without many different versions of the OS to confuse the heck out of you. Microsoft finally gave us the skinny on Windows 10's upcoming versions today -- and they're all pretty familiar to Windows fans. There's the usual "Home" version for mainstream consumers and the "Pro" version for business users. The latter is different from Windows 10 Enterprise, which is meant for bigger organizations with support for large-deployments. There's also a version of Windows 10 targeted specifically at schools, which is likely part of Microsoft's plan to take on Google's Chromebooks. On the phone front, Windows 10 Mobile is what you'll see on most consumer devices, but there's also a "Mobile Enterprise" version for businesses.
