General tab

Windows msconfig utility

The General tab is the default tab in the System configuration and shows how the computer will start, by default Normal startup should be selected. If you've changed any of the settings in the Boot tab or disabled any programs or services from starting up the Selective startup will be selected. If Selective startup is enabled and startup programs or services have been disabled, a notice will appear when the computer first starts letting you know that Selective startup is enabled.

Earlier versions of Windows such as Windows XP also included two buttons that were later removed. These two buttons were the "Launch System Restore" button, which opened the Windows System Restore feature and "Expand File" button, which allowed the user to expand any compressed file.

Boot tab

The Boot tab is an option added later into the System Configuration utility (Windows 98 and XP have boot.ini). This tab allows you to make the same adjustments you can make in the Windows boot.ini file without having to edit the file. In Advanced options, you can adjust such settings as the Number of processors to use during boot, maximum memory, and other debug options.

Services tab

Windows msconfig services tab

The Services tab allows you to enable or disable any of the Microsoft Windows services or other program services you have running on the computer. By checking the "Hide all Microsoft services" box at the bottom of the window, you can see all non-Windows services such as driver services and program services that are often the causes of startup problems. Unchecking a box will disable the service from starting.

Startup tab

Windows msconfig startup tab

The Startup tab is one of the most frequent reasons most Windows users enter the System Configuration utility. In the Startup tab, you'll be able to start and stop any of the programs (TSR's) that open each time your computer starts. These startup programs are often one of the biggest causes for a computer to startup and run slow. In Windows 8 Microsoft has removed this feature in the System Configuration utility and moved it into the Windows 8 Task Manager. Uncheck any program that you want to disable from starting up each time

Tools tab

Windows msconfig tools tab

The Tools tab gives you quick access to all the Microsoft Windows tools. For example, clicking the Event Viewer tool and clicking Launch the Event Viewer.

The SYSTEM.INI tab gives Windows 98 and Windows XP users quick access to editing and enabling and disabling the Window system.ini file.
