How Can I Tell What Is in My Startup Menu in Windows?by Brendan O'Brien
The Windows "Startup" menu lists the programs that run when your computer boots. Antivirus, firewall and other security applications launch with Windows to protect your computer from malicious software and websites. You may need to view and edit the contents of the "Startup" menu to troubleshoot your system if you have too many start-up programs. The more applications and programs set to launch with Windows, the less memory you have available for other tasks.
Click the Windows "Start" button in the bottom-left corner of your desktop.
Click "Run." Type "msconfig" in the text box, then click "Open." If running Windows 7 or Vista, just type "msconfig" in the search box a the bottom of the "Start" menu and press the "Enter" key.
Click the "Startup" tab in the window that appears. A menu of programs and applications set to run at system boot will display.
