If you would like to prevent users from using the Restart in MS-DOS mode command (one of the shut down options offered by Windows), here is the procedure:

• Run Windows Explorer and open the folder in which Windows is installed (we'll assume that it is C:\Windows).

• Find the following item: Exit To Dos (Shortcut to MS-DOS Program). Highlight it.

• Make a backup copy of this file (just in case). That is, while it is highlighted, press Ctrl+C, then press Ctrl+V. This should create a new file named Copy of Exit To Dos. If anything goes wrong, you can use it to restore the original file.

• Now, while Exit To Dos is selected, press Alt+Enter to open its Properties dialog. Select the Program tab.

• Change the Cmd line field to read as follows:

  C:\Windows\Win.com

  (If your copy of Windows is installed in a different folder, specify the correct path above.)

• Press OK to close the dialog.

Now, try to restart the computer in the MS-DOS mode (by choosing Shut down on the Start menu and selecting the Restart in MS-DOS mode option). The screen should go black for awhile, but eventually Windows should appear again, not MS-DOS prompt.

Note: This change affects all users of the computer.

Folder Guard offers a more elegant solution to this problem: Simply assign the no access attribute to the file Exit To Dos.pif, and this will restrict the Restart in MS-DOS mode command.
