Microsoft roll out Windows 10 with massive UK launch
Windows 10, the biggest update Microsoft has made to its computer software, has launched in the UK.
PC users across the UK stayed awake to wait for the updated operating system as the firm staggered its release, allowing some customers who pre-registered to get access before others.
The new software will be 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.
The Start menu is also making a return in the new software.
