Windows 10 Mobile is a phone-oriented version of the Windows 10 family of operating systems, which was released on 16 November 2015 coinciding with the launch of the Lumia 950[1] and the Lumia 950 XL.

It is the last release of the Windows Phone operating system family, as Microsoft ceased development of the operating system in October 2017 due to diminishing interest and application development for the platform and instead began to prioritize in software development and integrations with competing mobile operating systems.

On 21 December 2018, Microsoft announced that support for Windows 10 Mobile would cease on 10 December 2019,[2] although it was later extended to 14 January 2020.

Update system[edit | edit source]

Windows 10 Mobile updates were distributed via Windows Update as cabinet packages using the following suffixes:

  • .spkg, .spku and .spkr - old Windows Phone 8-style SPKG update delivery method, used to facilitate upgrades for devices that originally ran Windows Phone 8.1 to Windows 10 Mobile
  • .cbs, .cbsu and .cbsr - utilizes the modern Windows component-based servicing stack (CBS) to install feature updates and optional components on-demand

Most internal Windows 10 Mobile self-hosting builds were released to beta testers through the public Windows Update infrastructure, although only if the host device had a specific "super secret registry key" (SSRK) installed. Some builds (such as build 11069) additionally depend on the presence of the Microsoft.Tools.StudyID1510 feature to install. If a build is pushed to a device without it installed, the servicing stack will fail to process the update due to failing dependency checks.
