When
screenshots start leaking, typically a build will quickly find its way to the wild web. If the same pattern holds true with Windows 8.1 leaks, it looks like a build of the spring update for Windows 8.1 will leak in the near future.
The screenshot above does not show anything in terms of new features, but what it does tell us is that the spring update build is in the hands of quite a few people which means that a leak is far more likely.
The spring update will likely not bring a significant overhaul to the platform by any means and we will have to wait until
April of 2015 to see any major changes to the platform when Windows 9 arrives.
