1. There's loads of stuff for touch, but it's different stuff.
Microsoft says it wants to support touch users who have persevered with Windows 8 and "evolve" the touch UI. (Translated: That means it is changing quite a bit.) The task switching will no longer work on the left. So with that and the charms going, that's goodbye to most of the problem with Windows 8 - and a whole philosophy down the pan.
2. The Start Menu is back.
As I've covered before, the e most noticeable change is the new Start Menu, which looks somewhat like the old start menu. It brings some features from the Windows 8.1 Start Screen, such as live tiles, and can be resized.
3. Another New Task View.
Now the Windows 8 task switcher has been unceremoniously dumped, there's a new Task View in Windows 10, too, so users can switch between virtual desktops.That's because Microsoft now recognises that novice users use the taskbar rather than switching in other, cleverer, ways such as Alt+Tab (which also now switches between desktops).
4. Snap Assist helps you snap windows.
A new Snap Assist feature also helps users work out which way is best to snap apps to. You can snap windows into new screens and tile Windows - just as you've been able to since Windows 2.0 or maybe 3.0.
5. There is a big change in Command Prompt.
Another quite amazing feature for those of us that use it is that the command prompt is now getting keyboard shortcuts! So you will be able to paste in your commands! Hardly groundbreaking, but actually pretty exciting.
6. Improved Windows Explorer.
A new Home location is the new default view in Windows Explorer. There's also a Share button on the Windows Explorer task bar (we really hope this is in the context menu, too).
7. Continum (Special Feature)
This is the best new thing we found out today. Continum is an on-the-fly mode for 2 in 1 devices that can automatically change mode if it detects there is suddenly no keyboard attached. So, for example, a back button appears to help you navigate the Desktop with touch if the keyboard is removed. We reckon the charms will also disappear in non-touch mode, although we've heard conflicting news about that.
8. Windows 10 Universal Applications
Windows 10 will also usher in a new app model - Universal Windows apps. Windows Universal apps are the new name for Metro apps/Modern apps/Windows Store apps. Take your pick on those old monikers, they've got a new one! Presumably (although we don't know as yet) that these will also work on Windows Phone. Windows 10 will be able to run on all devices from phones to servers and there will be a single app store across the lot.
All older Windows Store apps will work with Windows 10.
9. Apps now float on Desktop
The new Universal apps also work on the desktop and 'float' in their own Windows. Microsoft wants to banish the separation between the Modern UI and the Desktop.
These 'modern' apps on the desktop have a ... icon for more options - replacing the commands that used to be in the charms on the right-hand side of the screen.
Microsoft says it hopes to appeal to business with this release of Windows, more so than Windows 8 ever did. Belfiore said they were "starting the dialogue with businesses today".
To be honest, it needs to - Windows XP is now ancient and unsupported, while precious other businesses want to make the leap away from Windows 7. But part of the reason why Microsoft is demonstrating the OS without all the consumer features is to show enterprises what the OS is capable of at this stage.
This version of Windows will have plenty of other features for enterprise, including a customised store and protection for corporate data. Mobile Device Management will be able to be used for all devices.Windows 10 will keep personal and corporate data separate.
