Microsoft has released another demo video for its new OS, Windows 8, and this time we get to have a look at Windows 8 Life ID integration, which will allow you to sign into a Windows 8 PC using your Windows Live ID.

"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,”

You can find out more information about the Windows 8 Live ID integration over at the Windows 8 Blog.
