What Is Windows 10X: Microsoft’s Folding PC OS Explained

The foldable computer is almost here, and there will be a version of Windows 10 for it. But maybe not exactly the one you know. It’s called Windows 10X, and it is the operating system that will power dual-screen laptops and folding PCs.

The operating system, which was codenamed Santorini internally, is based on the little-spoken of Windows Core OS. The brief version of Core OS is that it’s a stripped-down, simplified version of Windows that can be expanded or shrunk down to meet the needs of different devices.

Is Windows 10X like Windows 10S?

No. Additions can be made to that Core, and Windows 10X offers “newly implemented support for running Win32 applications in a container.” wrote Windows and education corporate vice president Eran Meggido in a blog post.  

That means that with Windows 10X, you won’t be limited to Universal Windows Platform (UWP) apps. What we don’t know yet is if there are further limitations to a stripped down version of Windows 10.

When will Windows 10X be available? What devices will it be on?

Windows 10X is currently scheduled to launch in the fall 2020. It will power Microsoft’s own Surface Neo, as well as computers from partners including Lenovo, Dell, Asus and HP. Each of these devices, Meggido wrote, will be powered by Intel (Surface Neo, specifically, will use one of Intel’s Lakefield chips).

Lenovo confirmed to Tom’s Hardware that its foldable ThinkPad X1 device will use Windows 10X when it launches. Asus would neither confirm nor deny if it will use Windows 10X for Project Precog

Don’t expect to see Windows 10X on conventional laptops.

What can Windows 10X do?

Frankly, we’re still in the dark on many of the specifics, though at its October event, Microsoft showed off some neat features that should make using a dual-screen device easier.

One of them was easy access to search. Another was that programs that are opened will show up on the side of the device in which it was invoked. And if you want it on two screen, you can pinch it and drag it to the center, which Microsoft referred to as “spanning.”

With the a Bluetooth keyboard (the Surface Neo has a magnetic one that covers part of one display), the “WonderBar” is invoked, with room for a touchbar, emojis, smaller screens or other menus.

Additionally, the extra space can be put to good use, like having Outlook in one window and opening new calendar invites or emails in the other without having to switch back and forth.

There may be a little more we know. At Computex, Microsoft corporate vice president of operating systems Roanne Sones detailed a vision for a more modern Windows. That included seamless updates, security, 5G and LTE and sustained performance. She also discussed cloud connectivity, the ability to fit on several form factors, and inputs from pens, touch and even gaze.

When will developers get their hands on Windows 10X?

Microsoft chief product Panos Panay said that part of the reason for debuting the Surface Neo early was to empower developers to build experiences for its two screens. Perhaps we’ll hear more about it at the next Microsoft Build, which will take place between May 19 and May 21 in Seattle in 2020.
