There are a lot of programs that load automatically when you boot up your PC, which can really hamper performance. To manage these programs like a pro, learn how to get a comprehensive view of what's running:
1. Click the Start button, and type System Configuration in the search windows. Select it from the list of results.
2. Select the Startup tab. The files set to run at startup are indicated with a check mark. You can uncheck nonessential programs, but make sure you only disable programs you're familiar with. When in doubt, leave it checked.
