The Start menu is back and you’ll find Live Tiles, which lets you personalise and customise the way Windows works for you – making the things that are most important available at your fingertips, according to Joe Belfiore, corporate vice-president for the operating systems group at Microsoft.
Windows 10 also integrates the Cortana personal digital assistant. Belfiore said Windows 10 PCs will offer face or fingerprint biometric authentication for logging in, through a service dubbed Hello.
There is also a new web browser, Edge, which enables users to save pages offline and annotate, either using a Stylus on a tablet, or via keyboard and mouse on PC.
The authentication process uses Microsoft Passport, in an attempt to protect users against phishing attacks that steal their login credentials.
