The System Configuration Utility (msconfig.exe) provides an intuitive interface for disabling startup items that are otherwise only accessible through the registry (i.e., there is no shortcut in the Startup folder in the Start menu). If you are not familiar or are uncomfortable with registry editing, use this utility.
To launch the System Configuration Utility:
In Windows 7 or Vista, in the Start menu, enter msconfig in the search field.
In other versions of Windows, from the Start menu, select Run... . Type msconfig and click OK.
Click the Startup tab.
Uncheck the items you do not want to launch on startup.
Note: It may take some time to identify which items to check and which to uncheck. Some items will be easy to identify (e.g., Microsoft Office), some may be slightly confusing (e.g., realsched), and some will be cryptic (e.g., 000StTHK or QFSSCHD110). If you cannot determine what an entry is (and therefore whether you should uncheck it or not), you may want to use a search engine to research the individual entry. Keep in mind there are some entries that you should avoid unchecking (e.g., virus scanners).
When you have finished making your selections, click OK.
In the box that appears, click Restart to restart your computer.
