HTC launched two Windows phone 8 devices last year namely the 8X and 8S and the company is certainly planning to stick with the OS, despite the fact that it pulled the plug on a device called Zenith, which was likely to be a WP8 flagship.

However, Unwired View now reports that the Taiwanese manufacturer is working on a smartphone called Tiara that runs on Windows Phone 8 GDR2, a second update to Microsoft’s mobile operating system after the recent “Portico” update, according to rumoured specifications.

Microsoft has said it will ship the preview the first week of June. If the company follows the same schedule it used in 2009 to deliver Windows 7′s release candidate, the most likely date is Tuesday, June 5.Eligible customers must purchase a new Windows 7-powered PC between June 2012 and January 2013.

The first wave of laptops with Intel’s latest third-generation Core processors started shipping this week with Windows 7, but PC makers are quiet about what it would take to upgrade the PCs to run Microsoft’s upcoming Windows 8.

The Windows 8 OS is due to come out later this year, though Microsoft has not provided a specific release date. Analysts have said that Windows 8 may come out around October, and a consumer preview version of the OS is already available for download.

It’s not often that Microsoft launches a dramatically revised version of Windows. But when the software giant does—as many expect with the launch of Windows 8—it’s big news.

And just about every industry stakeholder—from the company’s consumers to enterprise users to competitors—becomes interested in what the software will ship with and how it’ll fare in an environment so tied to past ideas. Until all that’s determined, however, many folks have questions.

Microsoft has detailed Windows 8′s minimum screen resolutions. The upcoming operating system will battle the iPad for tablet supremacy.

Microsoft is building Windows 8 to handle a wide range of screen resolutions. But it’s unclear whether hardware makers will take advantage.

Microsoft said it is building support for multiple screen resolutions into its new Windows 8 operating system, including support for resolutions that will match the new iPad screen’s sharpness and clarity.
