If there's an application you use all the time then you don't have to access it via the search system. Pin it to the Start screen and it'll be available at a click. Start by typing part of the name of your application. Right-click on the program tile on the Apps Search screen, and click 'Pin to Start'. If you're using a touchscreen, press and hold the icon, then flick down and select 'Pin to Start'.
Now press the Windows key, scroll to the right and you'll see the Control Panel tile at the far end. Drag and drop this over to the left if you'd like it more easily accessible, then click the tile to open the desktop along with the program window, then press the Windows key to return to the Start screen when you're finished.
