NOTE: MSConfig can be used to configure several things other than just startup programs, so be careful what you do with it. This tool is available and can be used to disable startup programs in Windows 7, Vista, and XP. 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. However, for most programs, starting them at boot-up just wastes resources and extends startup time. Disabling Startup Programs in Windows 7, Vista, or XPįor some programs, it’s smart to have them start with Windows, such as anti-virus and firewall software.
