Microsoft just released Windows 8.1 a few months ago, and already they are starting to highlight changes coming in Windows "Threshold". This is Windows 9 and it is supposed to be released in April 2015. The upcoming BUILD conference will be featuring this new OS from Microsoft and in my opinion if they don't hit this one out of the park, they may find their stadium emptying. On the heels of a chilly reception to Windows 8, they really need a winner here.
Windows 8 is tanking harder than Microsoft is comfortable discussing in public, and the latest release, Windows 8.1, which is a substantial and free upgrade with major improvements over the original release, is in use on less than 25 million PCs at the moment. That's a disaster, and Threshold needs to strike a better balance between meeting the needs of over a billion traditional PC users while enticing users to adopt this new Windows on new types of personal computing devices.
