Definition: Windows Phone 8


A major update to Windows Phone introduced in late 2012. It replaced the Windows CE operating system with a version of the Windows 8 operating system. Phones such as the Lumia 900, which cannot be upgraded to Windows Phone 8 may obtain some of its features with a Windows Phone 7.8 update.

Windows Phone/Tablet Compatibility
Windows Phone 8 apps do not run in Windows RT, 8 or 10 tablets. Microsoft took the opposite direction of Apple. Windows desktop apps run on Windows tablets, but Windows Phone apps do not. In contrast, iPhone apps run on iPads, but Mac desktop apps do not run on iPhones or iPads. See Windows Phone and mobile compatibility.
