Windows Core OS Family

Windows Core OS (formerly known as the Polaris Project) is a family of Windows operating systems created for tablet computers with two screens (like Surface Neo) and not only. The project was abandoned after the start of Windows 11 development and transferring all the innovations of the project there, but soon the project was unfrozen.
== Versions ==
In total, four versions of Windows from this family have been released. Each version was released after its main version (Windows 11, Windows 12, etc.) and was, in fact, a lite version of those.
* By the way, each codename of these versions denotes the main feature of the version or a reference to something:
** For example, the codename Windows 11X - Light, denotes ease and convenience in use.
** The codename of Windows 12X is Dusk Valley, refers to one of the innovations in this version - a super dark theme (for OLED).
** The codename Farlanese (Windows 13X) is a reference to the material from the Minecraft game (version 1.22).
** Dripstone (Windows 14X) is also material from the Minecraft game (version 1.17).

== History ==
The project was originally developed in 2018 and was named as Windows Polaris and was developed for single-screen tablets, and it was essentially a lite version of Windows 10. Soon one of the beta versions of Windows Polaris (Build 16299.241) was leaked to the internet, and the project was abandoned for unexplained reasons.
In 2019, the project is being restarted in Windows Core OS, as a universal operating system for tablets, computers, laptops and even smartphones. But soon the project was also closed.
In 2020, another system was leaked into the Internet, already called Windows 10X (Build 19578.1000). It was interesting for users, and they were waiting for a full-fledged release. Windows 10X ran on arm32 and 32-bit applications did not work in the system, but only UWP. But not everything is so good: and this project was closed. Microsoft has confirmed that instead of releasing Windows 10X as a separate OS, it will add key features of Windows 10X to the standard Windows 10, as well as its other products. But in the end, all the features and design of Windows 10X were transferred to Windows 11.
On January 14, 2023, the continuation of the Windows Core OS family called Windows 11X was announced. One of the builds (Build 22684.1 Developer Preview) was leaked to the Internet on November 26, 2022. At the stage of development, the system was codenamed Light. On June 29, 2023, the Windows 11X version was released. In fact, it was a lightweight version of Windows 11 on the arm32 architecture with a slightly updated design, but because of this, the version became more popular than Windows 11.
