Commenting on the low sales of PCs in generall, Reller said that the PC was very much alive and increasingly mobile. She added that the PC was part of a much broader device market of tablets and PCs, including new convertible devices and new touch laptops, and all-in-ones.
Microsoft will be rolling out an update to Windows 8, provisionally code-named 'Windows Blue', by the end of this year, Reller said. Details of the update will be released in the next few weeks.
"Windows Blue is a codename for an update that will be available later this year, building on the bold vision set forward with Windows 8 to deliver the next generation of tablets and PCs. It will deliver the latest new innovations across an increasingly broad array of form factors of all sizes, display, battery life and performance, while creating new opportunities for our ecosystem. It will provide more options for businesses, and give consumers more options for work and play. The Windows Blue update is also an opportunity for us to respond to the customer feedback that we've been closely listening to since the launch of Windows 8 and Windows RT. From a company-wide perspective, Windows Blue is part of a broader effort to advance our devices and services for Microsoft," Reller said.
Reller did not say whether the 'Blue' update would restore the start button, but she said Microsoft would pay more attention to helping customers adapt.
"We've considered a lot of different scenarios to help traditional PC users move forward as well as making usability that much better on all devices," she said.
Reller declined to comment on whether Microsoft would make a smaller version of its own Surface tablet.
