Microsoft has released an all-in-one Windows Live Services Suite beta installer similiar to Google Pack for Windows XP and Vista.

The installer is customizable and allows you to select from and add the following Windows Live applications:

Connect: Live Mail, Hotmail and Messenger
Find: Search, Toolbar and Gallery
Share: Spaces, SkyDrive, Photo Gallery and Writer
Protect: OneCare Family Safety
Homepage: Windows Live Home

Unlike Google Pack which includes software and applications from various third party providers, Microsoft offers only MS/Live services. In future, Microsoft may choose to include 3rd party programs from its partners.

Also, going forward, updates to the Windows Live Suite would be available through Automatic Updates for Windows Vista/XP.
