Reducing this is easy, it will make your PC launch noticeably faster and lighter upon first load. To change the items running at startup, go to Run using the hotkey Windows key + R, and type "msconfig." A small window will appear (see the screenshot below), select the Startup tab.
From here you will be able to turn off many startup programs, which can shave several seconds (or minutes) off your boot time. (Note Windows 8 has moved this functionality to the Task Manager). Try to make sure you research what you are turning off as some processes might be needed by third party programs or drivers you have installed.
