For starters, taskbar progress indicator support has been expanded to other built-in Windows functions, like hardware installation. Windows Live integration is evolving, too -- you'll be able to log in to Windows 8 using your Windows Live ID and have your avatar set to your local Windows profile picture. This also hints at further integration with the cloud.
There's also a lot of noise being made about an eight-minute Windows 8 install process, though if you've loaded Windows 7 from a bootable SATA hard drive onto a system you've already seen pretty similar speeds (and that's what the tester used, not a DVD). The post also refers to a factory restore function, which would roll back your Windows 8 installation back to its day-one glory in about two minutes.
It's also clear that excited Windows 8 leakers aren't paying any attention to Microsoft's not-so-subtle wallpaper. We're not entirely sad about that.
