Microsoft wants to catch up with mobile phone makers, HTC Corp, Samsung Electronics, Motorola and others.
The company has announced it will overhaul its phone software to help it regain momentum in the expanding Smartphone market.
Microsoft, realising Smart-phones are the key to the future of communications, is facing stiff competition from all comers, including arch-rival Google, with an Android system that already has a 4.7 percent share of the phone software market.

Microsoft took just an 8.8 percent of the global Smartphone operating system market last year.
Symbian, the system used on Nokia phones, has 47.2 percent of the market, while RIM’s BlackBerry has 20.8 percent and Apple’s iPhone comes in at 15.1 percent.
