Windows Phone OS - definition

Glossary

Windows Phone is a proprietary mobile operating system developed by Microsoft. Windows Phone introduced a new design language, previously called Metro UI, but later renamed to simply Modern.

Microsoft licenses the software to third-party hardware manufacturers, but keeps a stringent list of minimum requirements for the hardware it runs on to ensure the best user experience.

In 2011 Nokia announced it has chosen Windows Phone as the OS for all its future smartphones providing a solid backing for the fledgling OS and in the same time betting all of its mobile phone business on its success.
