Last year I wrote about Windows Lite. That never was a real name or at least I hoped it wouldn't be. However, now we have the first look at what it may be and the name is Windows 10x.
Back in 2015 Microsoft announced that Windows 10 was the "last version of Windows". True, if you mean there won't be something called Windows 11. There wont! What Microsoft has settled into is a series of updates that happen twice a year in spring and autumn. The older schedule of monthly security updates also applies. That is Windows we already know about.
However, for a long time Microsoft has wanted to modernise Windows. By modern we mean a more mobile style OS. The sort of operating environment that links to Microsoft's cloud services, is a lot less complex for daily tasks, is secure and updates like a phone.
They have tried. Windows 8 was a touch friendly move to get rid of old Windows. However, the PCs were not ready for such a radical change. Business users, who make the most money for Microsoft, were not ready for the move. So they staged a retreat. Similarly Windows RT, using ARM processors, looked like Windows but couldn't run traditional Windows applications and Windows 10 S ran only applications you could download from Microsoft's online store.
Each attempt had positive aspects but all failed because Microsoft were trying to marry the experience most people get on their mobile device with the requirement to run full screen applications like Word, Photoshop or Excel. Trying to get both things working proved to be a long road.
What they have come up with is firstly reducing Windows to it's core components. This is Windows Core OS (WCOS). This is designed to provide the fundamental things and operating system can do. On top of this is container technology. A container is a space where an application can run on it's own. The container has the application but also, and crucially, the parts of the operating system that make it run. Types of containers include traditional Windows applications, new web style applications and Universal Windows Applications (UWP). This latter category was the type of application that WindowsPhone was championing.
Windows 10X will first launch on dual screen devices. You won't see it on a PC near you soon. However, it might become the modern Windows that allows Microsoft to transition from the the PC world of the 1990s, where Windows started, to the lighter mobile applications and services environment of the 2020s.
