What's on tap for Microsoft's Build conference this week? Here's what we know and what we think we know.



From All About Microsoft:

At the developer confab this week, officials are expected to disclose fully the feature sets of the Windows Phone 8.1 and Windows 8 Update 1 operating systems. They also, according to sources, will share a bit about the next major version of Windows -- Windows 9, codenamed "Threshold," aka Windows 9, which is supposedly due to arrive in the spring of 2015.

Few expect Microsoft to unveil the full feature list or even the target arrival date for Windows 9 at Build 2014. Instead, Microsoft officials are likely to discuss at a high level the company's goal to create a new Windows 9 SKU that would run on Windows Phones, ARM-based Windows tablets/PCs, phablets and other kinds of devices. According to previous tips, this "modern" SKU might not include a Desktop for running legacy Win32 apps. It would be updated frequently and regularly by Microsoft through the Windows Store.
