Windows 10X (codenamed Santorini) was an edition of Windows 10 that had been in development by Microsoft as part of the Windows NT family. It was announced on October 2, 2019 as an operating system to support dual-screen devices, such as the Surface Neo. Windows 10X was originally expected to be released in 2020, On May 19, 2021, Microsoft announced that the project had been cancelled. Some of the features salvaged from 10X were incorporated into Windows 11.
On May 4, 2020, it was announced that Windows 10X would also support single display devices. The only way to access Windows 10X is to install its image file and Microsoft Emulator from the Microsoft Store.
On May 7, 2021, the Petri IT Knowledgebase reported that Microsoft was shifting development resources back toward Windows 10 updates and that work on 10X had been put "on the back burner, for now."
