The Windows 10 Consumer Preview made its debut at Microsoft’s launch event on Wednesday 21 January, where Redmond announced multiple hardware and software updates.

The company revealed that Windows 10 will be free for Windows 7 and Windows 8.1 users for the first year. During a Q&A after the presentation, executives declined to comment on the pricing structure after this time frame.

An 84-in device – the Microsoft Surface Hub – was also revealed along with the rumoured “Spartan” web browser.

Windows-as-a-Service will allow developers to work across all Windows devices, as well as improving security.

In terms of appearance, the task bar appears streamlined on Windows 10, and the Start Menu can be made full screen with a touch. Settings has also reverted back to look like the traditional Control Panel of old.

The Charms Bar also has a new look, with users able to swipe from the right to find a notifications panel. Swiping down will close all apps – not just Metro.

When the keyboard is removed from a hybrid device, the user will be asked whether they want to enter tablet mode, after which apps switch to full screen.
