HTC is reportedly being shut out of Windows RT development due to lack of experience in the tablet market, according to Bloomberg. The news doesn’t bode well for the Taiwanese vendor, which on Wednesday cut its second-quarter revenue projection by 13.3%. Microsoft’s decision to lock HTC out of Windows 8 development was due to concerns about the company’s tablet sales, or lack thereof; the publication’s sources suggest the software giant is worried that HTC may diminish and tarnish the Windows RT experience. HTC engineers were reportedly interested in building a Windows device with a customized home screen, similar to what the company does with its Sense UI on Android. Microsoft refused, however, and will instead work with other vendors that have achieved greater sales. HTC may still release a Windows device in the second round of products expected to launch next year.
