One of the main advantages of Windows has always been the program compatibility. The vast majority of Windows applications and games built in the last decade still work with the latest builds of Windows 1
Sources familiar with Microsoft's plans said The Verge that "Windows Lite" will be a slimmed-down version of Windows designed primarily for use on dual-display devices and cheap, Chromebook-style laptops. It will use a "composable shell," a modular version of the existing Windows shell, as well as components of the Microsoft core operating system (which drives the HoloLens 2).
According to reports, Windows Lite can at least in its current form only Universal Windows Platform applications (applications from the Microsoft Store) and the Web Run Apps. Support for legacy Windows programs may come later, for example, by running in protected containers. By removing the ability to run Win32 applications natively, Microsoft should be able to remove most of the previous bloat from Windows.
It's not clear when Windows Lite ships or if it's even the official name. Microsoft will hold its annual Build Conference in May, so we may learn more about the operating system.
Thank you, The Verge.
