1. New Refreshed UI
The most obvious change from Windows 8 to Windows 10 is the new user interface. It’s still flat and modern looking, but Microsoft went through great efforts to make it work for both touch screen devices and computers that rely mostly on a mouse and keyboard.
2. The Star Menu
It’s back, 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 re sized.
Windows 10 includes something that Microsoft has never offered in a desktop operating system before: a built-in virtual personal assistant Cortana.
4. Windows 10 Universal Apps
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
5. Virtual desktops/Task View
Task View, as Windows 10’s virtual desktop implementation is called, won’t appeal to everybody but it provides deep new functionality for power users. (The integration with windows snapping is especially handy)
6. Edge Browser
Microsoft has included a web browser with its operating system. Edge is a completely overhauled browser that’s lean, fast, and supports modern web experiences. It also includes useful features such as integration with Cortana and a note-taking mode that lets you doodle on a web page and share it with others. The first version of Edge will still be too bare-boned for power users. Digital inking tools let you easily mark up a website and share it with others.
7. Action Center
Notifications are one of the coolest features of modern operating systems, with popups reminding you of all sorts of useful information. Windows 8 had them, but those notifications disappeared forever as soon as they faded from your screen—an issue if you weren’t actively sitting in front of your PC when one popped up. The Action Center also provides quick-action buttons for common functions, like activating Blue tooth or connecting to a VPN, as well as an option for shifting the interface to Tablet Mode.
8. PC Gaming Experience
One of Windows 10’s most major changes can’t be overtly seen whatsoever: The new DirectX 12 graphics technology promises to revolutionize PC gaming.
Windows 10 has a new, cleaner lock screen that’s available to everyone. But if you have a laptop or PC with supported hardware, the new Hello feature will let you log in without ever typing in a password. Just sit in front of your computer, and Windows 10 will recognize you and log in. It’s similar to image recognition login systems. it’s far more foolproof thanks to the requirement of special cameras and infrared hardware.
10. Lots of Business and Enterprise Features
This version of Windows will have plenty of other features for enterprise, including a customized 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.
