Here are some highlights from the Windows Blog:
Start menu
The familiar Start menu is back, but it brings with it a new customizable space for your favorite apps and Live Tiles.
Everything runs in a window
Apps from the Windows Store now open in the same format that desktop apps do and can be resized and moved around, and have title bars at the top allowing for maximize, minimize, and close with a click.
Snap enhancements
You can now have four apps snapped on the same screen with a new quadrant layout. Windows will also show other apps and programs running for additional snapping and even make smart suggestions on filling available screen space with other open apps.
New task view button
There’s a new task-view button on the taskbar for quick switching between open files and quick access to any desktops you create.
Multiple desktops
Create desktops for different purposes and projects and switch between these desktops easily and pick up where you left off on each desktop.
Find files faster
File Explorer now displays your recent files and frequently visited folders making for finding files you’ve worked on is easier.
