Microsoft announced Windows 10X, a new version of Windows for dual-screen foldable devices. Microsoft promised that Windows 10 would be simple, sleek and faster than the current generation of Windows. The OS is now expected to launch on single-screen devices in the Spring of 2021. The operating system has now been updated to meet the growing needs of flexibility on low-end hardware and it’s likely to debut on mid-range devices. It is not something that you can install on current hardware and will not be released for beta testing.
