Where there's smoke, there's fire and now that the EU's caught a whiff of alleged misconduct on Microsoft's part, it's dragging Windows 8 under the hot lights. Though MS moved swiftly earlier this week to acknowledge and remedy the technical glitch that prevented users from selecting alternate browsers on early 2011 Win7 machines, it now faces similar claims from third parties regarding its upcoming Win8 tablets. According to Reuters, the European Commission's broadening its investigation to encompass allegations that Redmond is blocking the install of rival browsers on Win RT tablets running ARM chips and withholding access to full APIs. The company's yet to issue a response to this latest bout of legal drama, but when the stakes are this high, you can be sure it won't be before long.
