A history
Microsoft is giving up on its mobile OS aspirations for now. In Windows Phone, it produced a unique mobile OS; arguably the most original of the mobile OSes. Let’s see how it got there.
The journey to Windows Phone 10 was a colourful one that spans three decades and includes many devices, and several different operating systems.
This story starts with the launch of Windows CE 1.0 in 1996.
Windows CE was launched in 1996 by Bill Gates, and laid the foundation for Microsoft’s future mobile operating systems.
Referred to as Handheld PCs, the form factor of these devices was that of a small, portable PC, resembling more a tiny laptop than the mobile devices we’re used to today.
But mobile they were, generally weighing less than 450 g. CPU speeds were in the 40-50 MHz range, and they usually came with monochrome screens with resolution of around 480×240 pixels.
Pocket Internet Explorer was also introduced with CE 1.0. It did not share a codebase with its desktop counterpart—instead it was written from scratch to be lightweight.

| Input | 79 key keyboard Touchscreen Stylus |

Many regarded the first version of Windows CE to be a short-lived beta. With CE 2.0 Microsoft modularised the operating system, and expanded the number and types of device that could run it. Windows CE could now be used in diverse devices including cars, games consoles, and even kitchen utensils.
Supported architectures were ARM, MIPS, PowerPC, StrongARM, SuperH and x86.
Notably, Windows CE 2.0 added support for colour VGA screens, as well as built-in network support.
In all, there were 12 further updates to Windows CE 2.

Built-in apps included pocket versions of Microsoft’s Office suite, including Pocket Word, Pocket Excel, and Pocket Outlook, as well as Notes, a note taking app with handwriting recognition.
The Pocket Internet Explorer browser saw improvements too, with features like Shrink-to-fit which resized web pages for small screens.
Infrared (IR) file beaming was also supported.

Windows Mobile 6.5 was a stopgap update to Windows Mobile 6.1 intended to bridge the gap between version 6.1 and the then-to-be-released Windows Mobile 7.
This release was significant in that it saw the OS become more finger-friendly. It featured a slick new Today screen with large, clean, expanding, text elements—parts of this UI would carry over into Windows Phone.
It also included a hexagonal tile-based Start Menu, which was innovative, but ultimately didn’t stand the test of time.

Windows Phone 7 employed Microsoft’s Metro UI, a design language focused on typography and simplified icons, as well as Live Tiles, a fresh, colourful, tile-based home screen, with fluid transitions between screens. It looked markedly different to its predecessors, and offered a unique alternative to Android and iOS.
Microsoft laid down minimum hardware specifications for Windows 7 handsets, which mandated 5 physical buttons, for Start, back, search, camera, and power., as well as CPU, GPU, screen, and connectivity requirements.

Windows Phone RIP
In October 2017 Microsoft’s corporate vice president, Joe Belfiore, confirmed that, due to low market-share and lack of third-party development, Microsoft will no longer sell or manufacture new Windows 10 Mobile devices.
Existing devices will receive bug fixes and security updates only.
So long, Windows Phone. We will miss you.
