Description:
This gadget makes it easier to find help for Microsoft System Center products because it uses Live Search macros to search specific sites instead of the entire web. Search results are only returned from sites that are known to contain helpful information about System Center products. Use the settings in the gadget to pick the System Center product that you want to find information about, and then enter a search term in the gadget to get customized search results.
