According to various reports, the next version of Windows, codenamed Threshold, will reportedly arrive in March 2015. Notably, Threshold will incorporate a variety of features targeted at Windows "desktop" users who predominantly do work with their machines using a keyboard and mouse.
According to ZDNet, Threshold is being planned around a number of primary product versions, or SKUs, each of which would cater towards different types of devices.
Specifically, a "modern" consumer SKU will be catered towards Windows Phones, phablets and hybrid devices with an emphasis towards Modern apps. In addition, a "traditional" consumer SKU would offer the highest level of familiarity with users already familiar with a Windows PC.
Finally, an enterprise SKU will deliver all the usual features in the consumer editions, but with added support for group policy and device management, among other enterprise-centric features. And unlike the SKUs for consumers, the enterprise version might be subject to IT policies for organizations that do not want to automatically adopt Microsoft's (NASDAQ: MSFT) regular updates.
