Disable Programs at XP Start Up
1. Click on Start->Run
2. Type "msconfig" and click OK. (This will bring up System Configuration Utility.)
3. In the System Configuration Utility, Click the tab called Startup.
4. Now you can uncheck any programs that you do not want running at Windows XP startup.
5. Once you are done unchecking programs, Click Okay. You will be prompted to restart your computer at this point.
Have a nosy at google to find out what on earth some of these programs are before you disable ones you are not sure of for example I disabled aim6(aol instant messenger), steam (games application), and iTunesHelper.
