Disabling Startup Programs in Windows
For some programs, it's smart to have them start with Windows, such as anti-virus and firewall software. However, for most programs, starting them at boot-up just wastes resources and extends startup time. There is a tool installed with Windows, called MSConfig, that allows you to quickly and easily see what's running at startup and disable the programs you prefer to run on our own after startup as needed. This tool is available and can be used to disable startup programs in Windows 7, Vista, and XP.
NOTE: MSConfig can be used to configure several things other than just startup programs, so be careful what you do with it. If you're not sure about using it, just follow the steps in this article and you should be fine.
To run MSConfig, open the Start menu and type "msconfig.exe" (without the quotes) in the Search box. As you type, results display. When you see "msconfig.exe," click on it or press Enter, if it is highlighted.
NOTE: If you are using Windows XP, open the Run dialog box from the Start menu, type "msconfig.exe" in the Open edit box, and click OK.
Click the Startup tab on the System Configuration main window. A list of all the startup programs displays with a check box next to each one. To prevent a program from starting up with Windows, select the check box next to the desired program so there is NO check mark in the box. Click OK once you have made your choices.
A dialog box displays telling you that you may need to restart your computer for the changes to take affect. Click Restart to restart your computer immediately. If are not ready to restart your computer, click Exit without restart.
