Main features of Windows 10 operating system

Information and interests
With the "Information and interests" feature on the Windows taskbar, users can quickly access integrated feeds of dynamic content, such as news, weather, sports, etc., which are updated throughout the day. Users can also personalize the taskbar with relevant content that they are interested in, and read information seamlessly from the taskbar, while the content is relatively concise so it is less likely to disrupt daily workflows.
Biometric technology
The new Windows Hello feature in Windows 10 will bring a series of support for biometric technology. In addition to the common fingerprint scanning, the system can also log you in through facial or iris scanning. Of course, you need to use the new 3D infrared camera to get these new features.
Cortana search function
Cortana can use it to search for files on the hard drive, system settings, installed applications, and even other information on the Internet. As a personal assistant service, Cortana can also help you set time and location-based reminders like on mobile platforms.
