The Run command, which was available in the Start menu of Windows 2000 and Windows XP, is not visible in Windows Vista.
Most keyboards have a Windows key, usually located between the Ctrl and Alt keys. If you hold down the Windows key and press 'R', a Run prompt will appear.
This may be useful if you need to start msconfig in order to limit start items, or msinfo32 to gather system information files (files with a .nfo extension).
Msconfig has added a Tools section. Several common tasks can be managed from here, including Regedit, Event Viewer, System Information, Command Prompt, and Task Manager. (See the images below.) To open one of these tasks, highlight the task and click Launch.
