Windows 10 returns the Start menu and adds a service model

Windows 10 brings back the Start menu while keeping the tile-based ideas introduced in Windows 8. Task View and virtual desktops give users clearer ways to manage open work.

Microsoft also introduces Edge and Cortana, tying the desktop to newer web and assistant experiences. The operating system is meant to adapt across PCs, tablets, and hybrid devices.

The biggest change is the delivery model. Windows 10 is presented as an ongoing platform, so updates and services become part of how the product evolves after launch.
