IE10 on Windows 8 isn't doing anything that you can't already do on Windows 7 with the Live sign-in assistant plug-in though, including things like signing into C9 without ever typing in your password in IE.

Point is, in Windows 8 it's out of box without installing anything. IE gets the same live credentials you use at the Windows login screen, without any asking, confirmation or warning.

Is this something only IE has access to? If it is open to all programs, I see some malware potential with this.
