New era for Microsoft as Windows 10 is rolled out

Windows 10, the biggest update Microsoft has ever made to its computer software, was launched overnight.

The new software is the first to work across all Windows-powered devices, from smartphones to tablets and desktop computers, as well as Microsoft’s Xbox One games console.

Microsoft is also introducing a new web browser — Edge — to replace Internet Explorer, while the firm’s voice assistant Cortana will also move to desktop computers for the first time.
