7. About Windows Technical Preview
Tech Preview is the first pre-release build of the next version of Windows.
Tech preview is different from previous releases in four key ways:
1. Instead of a full build, this preview is a subset of what’s to come.
2. Microsoft releasing bits at earlier stages of the development process.
3. With the participation of more users around the world, Microsoft expecting
the most robust set of feedback.
4. We’re delivering updates in an ongoing cycle of development-feedback-
refinement, making development a joint effort between developers and users.

10. User interface and desktop
Windows 10’s user interface changes its behavior depending on the
type of device being used and available input methods.

11. Continuum
Continuum handles transitions between interface modes on convertible
laptops and tablets with docking keyboards.
Continuum Mode :- On 2in1 devices, Windows 10 will move easily
between keyboard/mouse and touch/tablet as it detects the transition
and conveniently switches to the new mode.
If you remove the keyboard/mouse, a notification will pop up from the task bar at
the bottom, asking if you want to activate Tablet mode.
Place your tablet into the keyboard again, and you’ll receive the same prompt,
this time asking if you want to exit Tablet mode.

12. Start menu

organized
when click on the Start button at
the bottom left of the screen, you
get two panels side by side, with
the left column showing pinned,
recently added and most-used
apps.

20. Project Spartan browser
A new web experience for Windows 10 – Code-named “Project Spartan,” the next
generation browser was built with greater interoperability, reliability and
discoverability, with a new look and feel built just for Windows 10.

contextual information from the sites
Integration of Cortana for finding and doing things online faster.

24. The new Microsoft browser is going to be powered by a new rendering engine,
EdgeHTML.dll. Windows 10 already has it integrated, and it will be separate from Trident
(MSHTML.dll) that powered Internet Explorer for decades.

performance.

We get the feeling there’s a lot more for Microsoft to share about Windows 10, and
we won’t get to see it until the Microsoft Build Developer Conference in April 2015.
