Each Windows user wants to have the ability to set up and use a PC in a way that is unique to them. Doing so, however, can be challenging in today�s multiple user and multiple PC environment. We know that shared PC usage is common and we�ve heard from many of you that switching between multiple accounts can be cumbersome. The difficulties associated with managing multiple accounts often lead to the sharing of a single account on a PC, and a less personal (and potentially less private) experience for each user. We also know that users are utilizing multiple devices more often now, and setting up a new PC can be inconvenient and time consuming. In Windows 8, we have set out to ensure that each PC user has a truly personal experience that seamlessly bridges their online and offline tasks, is simpler to set up and use, and persists across their set of Windows 8 PCs. To do this, we�ve introduced the ability to log in to Windows (optionally) with a Windows Live ID that works across devices, apps, and services, allowing you a uniquely personal experience with Windows.
