Live Search Macros for Microsoft Professionals

Live Search allows creation of macros to customize and confine your searches to a group or community of sites. You can also share macros for others to use, and many of them can be found at Gallery.

Some of my favorites are:

1. MSDN 
2. MSDN Blogs
3. Microsoft Forums
4. Microsoft Support
5. Visual Studio Tools for Office
6. Microsoft SharePoint Community
7. Microsoft SharePoint
8. Windows Mobile
9. Windows Vista Help
10. Video Games

Add any of above as Search Provider in Internet Explorer from here.
