Boost Start menu in windows Vista

[Isaac1]

You can customize the search results returned in the start menu search box to only return the results that you want. As you execute a search, Windows Vista automatically searches the file index as well. Go to your Start Menu and narrow down the scope of the search. You can boost searching in your Start Menu by narrowing the scope of the search by following ways:
Registry Editor

• Open registry editor using regedit.
