Windows 10, the biggest update Microsoft has made to its computer software, has finally launched after a massive beta test programme.

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.

The firm is allowing some customers who pre-registered to get access before others.

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 much-loved Start menu, which was removed in Windows 8 to much public outcry, is also making a return in the new software, as the US-firm looks to modernise and appeal to a new range of customers.

Millions of PC users will also be able to upgrade for free as Microsoft is making the update available at no extra cost to those who are already using Windows 7 or 8, though this offer will expire next year.
