Msconfig
Msconfig, also known as the System Configuration Utility, is a Microsoft utility introduced with Windows 98 and available in all later versions of Windows. It is used to configure how a computer starts and what programs and services load when Windows starts. Users running Windows 98 or later versions can open msconfig by following the steps below.

Click any of the links below for additional information and examples about each of the available options.
General tab
The General tab is the default tab in the System configuration and shows how the computer starts. 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. When the operating system uses Selective Startup, it gives you a reminder notification that Selective Startup is being used.
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 the "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 lets you make the same adjustments you can make in the Windows boot.ini file without editing the file. You can adjust additional settings in Advanced options, such as the number of processors to use during boot, maximum memory, and other debug options.
Services tab
The Services tab lets you enable or disable any Microsoft Windows services or other program services you have running on the computer. Check the "Hide all Microsoft services" box at the bottom of the window to only see non-Windows services such as driver services and program services. Unchecking a box disables the service from starting.
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 (TSRs) 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. Uncheck any program that you want to disable from starting up each time.
In Windows 8, Microsoft has removed this feature in the System Configuration utility and moved it into the Windows 8 Task Manager.
Tools tab
The Tools tab gives you quick access to all the Microsoft Windows tools. For example, you can access the Event Viewer tool by selecting the Event Viewer option in the tool name list and clicking the Launch button.
SYSTEM.INI
The SYSTEM.INI tab gives Windows 98 and Windows XP users quick access to editing and enabling and disabling the Windows system.ini file.
WIN.INI
The WIN.INI tab gives Windows 98 and Windows XP users quick access to editing and enabling and disabling the Windows win.ini file.
BOOT.INI
The BOOT.INI tab gives Windows 98 and Windows XP users quick access to editing and enabling and disabling the Windows boot.ini file.
