Microsoft has announced the availability of their Windows Live ID utility which handles username and password management of various Windows Live Services such as Windows Live Home, Hotmail, Spaces to name a few.
Through the online provider, the Sign-in Assistant helps a Windows 7 application running on one computer identify and communicate with other computers that are associated with the same Windows Live ID. Just by linking your Windows Live ID to the user account on each Windows 7 computer you own, you enable those computers to identify each other and work together more easily than has been possible in the past.

Windows 7 currently includes a new Credential Manager Control Panel item which handles username and password credentials for various websites other than Windows Live and computers that you may access on your network. I will take a look at it later this week, its very handy and is a cinch to backup and restore on new PC’s running Windows 7.
