COMMAND WINDOW POPS UP AND DISAPPEARS WINDOWS

The solution is to run a Windows Command Prompt and type the original command into the resulting command-prompt window.

The program reported an error of some sort, and immediately exited.

The program is a character-mode program.

The most common cause of a quick flash after typing a command into Start-RunВ is that: The correct way to do so is to run Command Prompt вЂњas administratorвЂќ, and then run the command therein. In this case, SFC requires that it be run with Administrative privileges enabled. By starting your ownВ Command Prompt, you control when the window closes. When runВ from Start-Run, this message was lost, as the Command Prompt wasВ automatically opened and quickly closed when SFC finished. You can see that SFC has run, printed a message, and exited. Now, in the command prompt, type вЂњSFCвЂќ followed by Enter. The Windows Command Prompt is a character-mode interface that you can work in. You can once again use Windows key + R, and enter вЂњCMDвЂќ followed by clicking OK, or you can locate the Windows Command prompt in the Start menu. You should see a window come up and disappear quickly - in a flash - and not much else. Into that box, type вЂњsfcвЂќ to run the System File Checker.Д¬lick on OK. Hold down the Windows key and type вЂњRвЂќ to bring up the вЂњRunвЂќ dialog box. The вЂњflashвЂќ youвЂ™re seeing is just the Windows Command Prompt opening and closing quickly as all that happens in a flash. Windows automatically closed the Command Prompt window.The program finished - quickly - and exited.The program ran within the Windows Command Prompt.Windows automatically started up the Windows Command Prompt.Windows located the program you asked it to run, and determined it to be a character-mode program.You typed your command into WindowsвЂ™ вЂњStart RunвЂќ dialog and clicked OK.The window youвЂ™re seeing flash up is a Command Prompt window. When the character-mode program youвЂ™ve run exits, Windows automatically closes the Command Prompt it started. That вЂњenvironmentвЂќ is the Windows Command Prompt, though old timers often call it the вЂњDOS box.вЂќ For a GUI application, that means вЂњrun it normallyвЂќ in Windows.ДЇor a character-mode application, though, Windows first starts up aВ character-mode environment for the application to run in, and then runs theВ program in that environment. When you run aВ program, either by double-clicking an icon, selecting a menu item, or using Start-Run, Windows takes a look at the program, determines what kind it is, andВ вЂњdoes the right thingвЂќ. Windows supports both GUI and character-mode applications. To start the old character-mode versionВ of Microsoft Word, youвЂ™d type вЂњWordвЂќ, followed by the Enter key, and MS-DOS would run Word. Instead, you typed in certain commands, or the name of the program you wanted to run, pressed Return, and MS-DOS wouldВ locate the program and run it. Without graphics, character mode had no menusВ or icons to click on to run programs. MS-DOS, the pre-cursor to Windows, was built using a character-mode user interface. Character mode explicitly does not supportВ pictures or graphics of any kind. The key is that in character mode, the only thing that can be displayed on the screen are characters. Your mail program, webВ browser, text editors, word processors, and more all display various graphical user interface components, including fancy icons, colorful images andВ controls, and just about anything that can be drawn on the screen.Д«efore there was a GUI, there was what we now call вЂњcharacter mode.вЂќ A вЂњcharacterвЂќ is a letter, number, or special item, including punctuation marks. YouвЂ™re most familiar with programs that sport a Graphical User Interface, or GUI. The fundamental problem here, if you want to call it that, is that there are two types of programs. TheВ good news is, thereвЂ™s a simple trick that covers it: run a Windows Command Prompt, and type your command into that instead. Start-Run is incredibly useful, but itвЂ™s not appropriate for everything. ItвЂ™s only obvious if youвЂ™ve been using PCs since before there was Windows, and before there was a GUI.
