Windows 10X (codenamed Charles de Gaulle (CDG); named after the airport of the same name) is a canceled version of Microsoft Windows, intended for both single-screen and dual-screen tablets. It is based on Windows Core OS in a similar fashion to the ill-fated Polaris project. Development of the operating system was announced on 2 October 2019[1] and was subsequently halted in February 2021;[2] it was eventually canceled in May of the same year, with some key functionalities being incorporated to Windows 11 and other Microsoft products.[3]

The operating system featured a new GUI stack using DirectX and UWP. Although it still contains the Win32 subsystem, the base system does not include the old USER/GDI stack and legacy Win32 apps have to run virtualized, either using remoting or a purpose-built container.[4]
