Application launching on a computer via indexed data. Based on a search term entered by a user, the computer searches an index containing metadata representative of one or more applications installed on the computer. A user interface on the computer's display has a window for displaying the results of searching the index. In addition, the user interface receives user input to select an application from the search results to be initiated. The computer is responsive to the user input via the user interface for initiating the selected application installed on the computer. A computer-readable medium including a persistent component, an index component, a query component, and an execution component embodies further aspects of the invention.
