Microsoft on Tuesday offered its first glimpse of its Windows 10 software that it hopes delivers a winning formula for powering tablets and smartphones, along with laptops and desktop computers.

The US software colossus focused on its core business market while unveiling an “early technical preview” of next-generation Windows software slated for release next year.

An “Insider Program” for developers who want to dabble with Windows 10 and provide feedback will kick off on Wednesday.

“Windows 10 represents the first step of a whole new generation of Windows, unlocking new experiences to give customers new ways to work, play and connect,” said Microsoft operating systems group executive vice president Terry Myerson.

“This will be our most comprehensive operating system and the best release Microsoft has ever done for our business customers, and we look forward to working together with our broader Windows community to bring Windows 10 to life in the months ahead.”

Pressure has been on Microsoft to win over companies that have shunned the current version of Windows, which was radically overhauled to adapt to the booming popularity of computing devices with touch screen controls.

While Windows 8 was tuned into personal lifestyles rich with smartphones or tablets, it was not a hit at companies where people still work using traditional computers with keyboards and mice.

More than a year after its release in late 2012, the number of businesses using Windows 8 were vastly outnumbered by those using Windows 7 and even using Windows XP, according to market trackers.
