Using MMC command-line options, you can open a specific snap-in console, open MMC in author mode, or specify whether the 32-bit or 64-bit version of MMC is opened.
mmc <path\filename>.msc [/a] [/64] [/32]
<path\filename>.msc Starts MMC and opens a saved snap-in console. You need to specify the complete path and file name for the saved console file. If you do not specify a console file, MMC opens a new snap-in console.
/a Opens a saved snap-in console in author mode. Use to make changes to saved consoles.
/64 Opens the 64-bit version of MMC (MMC64). Use this option only if you are running a Microsoft 64-bit operating system and want to use a 64-bit snap-in.
/32 Opens the 32-bit version of MMC (MMC32). When running a Microsoft 64-bit operating system, you can run 32-bit snap-ins by opening MMC with this command-line option when you have 32-bit only snap-ins.
You can use environment variables to create command lines or shortcuts that do not depend on the explicit location of console files. For instance, if the path to a console file is in the system folder (for example,
mmc c:\winnt\system32\console_name), you can use the expandable data string %Systemroot% to specify the location (
mmc %Systemroot%\system32\console_name.msc). This may be useful if you are delegating tasks to people in your organization who are working on different computers.
When snap-in consoles are opened with this option, they are opened in author mode, regardless of their default mode. This does not permanently change the default mode setting for files; when you omit this option, MMC opens snap-in consoles according to their default mode settings.
After you open MMC or a console file in author mode, you can open any existing console by clicking Open on the Console menu.
You can use the command line to create shortcuts for opening MMC and saved snap-in consoles. A command-line command works with the Run command on the Start menu (if the Classic view of the Start menu is selected), in any command-prompt window, in shortcuts, or in any batch file or program that calls the command.
