Windows Phone 8 operating system launched by Microsoft

Microsoft has formally launched the Windows Phone 8 operating system in a bid to reclaim smartphone market share.

It boasted that the system's internet browser, Internet Explorer 10, was the fastest on any mobile, and also suggested it offered the closest integration with video chat app Skype.

Microsoft had a 3.1% share of the handset system market in the April-to-June quarter, according to IDC.

The low figure has discouraged some developers from building apps for it.

HTC, Nokia and Samsung have all unveiled flagship WP8 devices over recent months, but had been unable to release them while they waited for Microsoft to sign off its software.

The handsets will now go on sale in Europe at the weekend and rollout worldwide during November.

"It can't be underestimated how important it is to Microsoft to get a successful handheld platform," Ben Wood, director of research at CCS Insight, .

"It's the fastest growing and most prolific sector - 800 million smartphones will be sold this year, within three years that number will be up to one billion annually. Nokia has also bet the ranch on this at a time when the market is dominated by Apple and Google's systems - and Microsoft is seen as being late to the party."

Kid's Corner

WP8 resembles the Windows 8 PC operating system released last week. Users navigate the interface by swiping through tiles which also display information pulled from the internet - for example weather conditions, Facebook status updates or recently received emails.

While its predecessor WP7.5 was based on the firm's ageing Windows Mobile platform, WP8 shares its kernel - or software core - with its PC equivalent, which should help make it easier to port programs between the two environments.

Much of the details of WP8 were announced at a previous event in June. But Microsoft had held a few features back until the San Francisco launch.

Kid's Corner feature

These included the speed of Internet Explorer 10 which it said was up to seven times faster than the version on WP7.5 at handling webpages based on the commonly used Javascript language. In addition it has been designed to make use of devices' graphics processing units (GPUs) to render videos or animations written in the HTML5 computer language.

The firm also showed off Kid's Corner - a function designed for parents who give their handsets to their children to play with. It allows them to restrict access to a limited number of apps without giving access to email, phone call or text message functions.

Microsoft said a survey had suggested about two-thirds of smartphone-owning parents in the US had used the handsets to occupy their children while out shopping, visiting friends or some other activity.

Another new feature is Rooms which allows users to create an invitation-only environment in which members share their calendars, notes, photos and other material. The firm suggested it might be used to help families, sports teams and other community groups stay "in sync".

Microsoft also made much of an "always-on" Skype experience.

This addresses one of the major flaws with its previous mobile system which had not allowed the video chat program to run in the background. That had meant that users of iOS and Android phones had been able to receive calls while using other apps, but WP7.5 devices had not - a notable omission bearing in mind Microsoft paid $8.5bn (£13.7bn) to buy Skype in 2011.

On WP8 Skype runs in the background even if the app is closed and the phone locked. It uses a similar method introduced in the full Windows 8 system to reduce its battery use by effectively being "asleep" until an incoming notification of a call wakes up the program.

Microsoft stressed the facility would also be available to other video chap apps including Tango and Qik so that its own program would not be given an unfair advantage.
