Major leak reveals more about Microsoft Windows 10X

When Microsoft revealed the Surface Laptop 3, Surface Pro 7 and Surface Pro X recently, it also revealed Windows 10X, a version of Windows 10 optimized for dual-screen devices. At the time, details were not extensive, but now a major leak sheds some light on what we can expect to see.

Documentation for Windows 10X (or Santorini OS) has appeared online, revealing that Microsoft will also allow the operating system to be run on more traditional laptops. There are also some intriguing screenshots that give us a glimpse into the future.

Thankfully, the text and images were grabbed by others, and shared by German website Dr Windows. You can see the contents of the document here, and you'll notice references to the codename Santorini OS:

Launcher

Launcher helps users start and resume tasks quickly. Search is seamlessly integrated with web results, available apps, and specific files on your device. Next up in the hierarchy of content is your default app grid, which can be customized and rearranged to meet individual needs and preferences. This relatively static set of apps drives predictable views each time Launcher is opened and further assists in accelerating users with the use of muscle memory over time. And lastly, Recommended content is dynamically updated based on your most frequently and recently used apps, files, and websites. Jump back into your personal workflow without having to start from scratch.

Lock/Logon

Logon has a simple job: get you to your stuff as quickly as possible.
With the Restrained Lock model, when the screen turns on you are immediately brought to a state of authentication; unlike Windows 10 where you first need to dismiss the Lock Curtain before authenticating. Users are encouraged to set up Windows Hello facial recognition as well as a Windows Hello PIN during OOBE. Upon waking the device, Windows Hello Face instantly recognizes the user and will immediately transition to their Desktop.

Goals & Principles

Quick settings

Quick settings provides a fast and intuitive way for users to access their commonly used settings. Today, settings exist in multiple surfaces and there isn’t a clear and consistent path for users to access the settings that are most important to them.

Goals & Principles

Efficient
Users can quickly modify their critical device settings

Focused
Only show important device settings so users are not distracted by other settings

At A Glance
Quickly see the state of your device

Relevant
Give users power to tailor the surface according to their needs

Structure & Scope

The quick settings surface has 2 levels of settings: L1 being the main quick surface, while the L2 is available when more lightweight settings detail is required.

Defaults:

• Wi-Fi
• Cell Data
• Input Language
• Compose Mode
• Bluetooth
• Airplane Mode

Taskbar

Goals & Principles

• User can switch between applications on the taskbar
• User can launch applications and websites from the taskbar
• User can pin and arrange applications and websites for frequent use
• User has entrypoints to launch Start, Task Switcher, and Quick Actions

Structure & Scope

• Running website: Active web tab within a window, can either be in foreground or background
• Glomming: Taskbar behavior where multiple instances of an app are grouped t ogether under the same icon
• Active state: Highlight on taskbar icon which appears when that app is active/in focus
• Running state: Behavior where the taskbar icon is underlined when an app is running, whether the app is in focus or not
• Extended Ul: Glomming behavior where on taskbar icon hover a Ul appears with thumbnails for the various instances of that app
• Recent app: App which was launched recently. Can be running or not running to appear on the taskbar
• System status: Collection of icons that indicate critical system status information System status bar Bar that runs across the length of a screen, contains the System Status; synonymous with "Minimized Taskbar"
• Stacked system status: View of the system status that seen when the system status is on the Taskbar, laid out to fit the space of one icon

Taskbar model

For both clamshells and foldables, the taskbar will be the same base model with a series of "levers" which can be pulled to create some alternatives in the model. We want to build these levers to address the deltas between the two experiences, while still building off the same initial model.

Levers include:
• Centered vs. Left-aligned Taskbar content
• Number of pins
• Number of recents
• Order of recents (recency vs. reverse recency)
• Divider vs. no divider
• Task View icon at far right vs. next to Start
