Microsoft is revealing more about its Windows 10X operating system today, which is designed for new dual-screen devices. From a report: The software giant has re-engineered this special variant of Windows 10 to install and update the operating system a lot faster. This will allow Windows 10X to download an OS update and simply switch to it at reboot, all within less than 90 seconds. That’s a big difference from what we’re used to with Windows 10 today, which involves the OS downloading an update and then applying it and rebooting. This takes minutes even on high-end systems currently, but Microsoft has developed a special state separation in Windows 10X to improve this radically.
