HTC One (E8)
HTC One E8, Desire 616 Officially launched in IndiaHTC Blog

Taiwanese smartphone maker, HTC is reportedly working on the Windows Phone OS based One M8.

HTC is testing Windows Phone OS version of the company's flagship handset One M8, according to Tom Warren's (reporter, The Verge) tweet message.

The company has already released two HTC One M8 variants-  one, a compact model One Mini (aka One Remix for Verizon model for the USA) and another One E8, a plastic model and now if things go as planned, we might see the new HTC One M8 with Windows OS boasting virtual voice-assistant Cortana by the end of 2014.

Unlike plastic based One E8, the upcoming HTC Windows handset is expected to feature all specifications seen inside the flagship One M8, including ultra-pixel based dual-cameras on the rear side and metallic body (90 percent, to be precise), reported WMPoweruser.

Technology website The Verge claims that HTC is currently trialing dot-view cover case for the Windows phone variant. However, it remains to be seen how the company will incorporate custom Sense UI (with BlinkFeed) in the 'Metro' inspired Tiles interface seen in Windows based handsets.

Even though the rumors of Windows powered HTC One (M8) is running wild in the media, HTC is yet to respond to them. Until the company clears the air over the rumors, this report will remain as pure speculations only.

If this rumor really turns out to be true, it is certain to boost the morale of Microsoft, which is currently trailing at a distant third (behind Google Android and Apple iOS) in the top Mobile OS chart. Windows Phone OS has a mere 3.7-percent global market share, reported IDC (International Data Corporation).
