All comments about mmc.exe:
Microsoft Management Console - this is normal in Windows 2000 and XP, should be located in system32. It is used by several snap-ins, such as the defrag console, the user management console, etc. Capi
Nothing to worry about OMGWTFBBQ
this is the application that shows you hardware specifications of you computer, it's not dangerous El Mariachi
After defrag my Win 2000 Pro SP4 NL windows said it had to close mmc.exe because of some wrongs it did. This computer has NO Internet connection,and i installed Win 2000 Pro as a upgrade for Win 98 SE. Because it has no internet connection,i do not think mmc.exe has anything to do with a virus or spyware. Karanskoff
mmc.exe is the Microsoft Management Console application and is used to display various management plug-ins accessed from the Control Panel, such as the Device Manager. This program is a non-essential system process, but should not be terminated unless suspected to be causing problems. KGBspy
I dont think its required to run windows successfully, but im not about to kill it if it does no harm to my computer. Look for other stuff to kill! Snake Solid

with my 64bit AMD PC running windows 2000 pro load, running defrag software on my large drive (mine 250G) to defrag, I got mmc.exe error and my system was totally crashed (1st crash caused me a total Win 2000reload) and (2nd crash which I'm debugging because I made ERD but it still have not recover. One change made to system.sys helped a little but still need nvidia driver nv4_mini. Do not defrag unless you make backup of your files. Steven
nothing. somehow it got listed in my antivirus block list (either by the program itself or my own ignorance) for two weeks and i didn't see any adverse effect on the pc egoman
Never heard of anyone having a problem with mmc, pops up in task manager when defraging then goes away. daviej
Part of Windows - non essential for most users - disable via run: services.msc. Stoob
i dunno what it does, apparently has to do with defrag and such. my computer constantly read 100% CPU usage, and lagged constantly until i terminated it. terminating it got rid of 95% of my cpu usage and now my computer doesn't lag at all..... LordFrog
search engines cure stupidity
mmc.exe is the process on my AMD 64 Vista machine with the most hard faults. I once saw it at over 100/min! Chris

I have heard that defragging newer, larger hard drives can actually damage them Mike Doherty
If you use Ctrl-Alt Del an have the taskmanager window on screen the process mmc.exe is running. No harm. I have no problems with it Erik Bolding
Expect it to blow up + 100mb and swamp your system. Rob Williams
its a part of win2k and winxp you morons
It's part of the windows defragger tool. Saw it in my process list when I paused my defragging, googled, it, NOT harmful at all. Unless of course it is a hidden version. Bob Heinbokel
all I know is so far it's only come up on my processes one time, and it was eating up all my CPU's Andrew
MMC is a windows system file, but the file name is used by virii. Check the location of the file to insure whether or not it is the legitimate file, or not. Muknuk
this is a console to manage events,user,group permissions,services etc... kalyan
I have been trying to run defrag and in task manager, there are multiple mmc.exe. I believe that it is a virus in disguise becuase many of my prgrmas have been malfunctioning and the problem is worsening. GilroyGroup

MMC is a file used in servers to manage users and group policies, there is no risk involved with the program and it also an inbuilt feature of XP, Vista and Windows 7 server editions and Home Editions to simply view and get a taste of this file just go Start RUN MMC It stands for Microsoft Management Center. Do not stop this process! Steven Pollock
mmc.exe is required if you want to use the Windows GUIs to defrag your disk, manage services, manage computer devices and much more. removing it brings no great joy, and plenty of headaches when things go bad Steven
The MMC is an application management framework that provides a consistent interface and methodology for implementing and using system administration tools. Annapurna Sengupta
It runs some things in the system such as control panel and task manager and device manager. If device manager is acting up, check your registry. Mark Sokolovsky
its the management console... you can safely kill this Row
it is Microsoft Direct Play kind of like flash but it's a very important system file Shashin Patel
I can't access my computer because of mmc . I am not able to delete unwanted files, and my computer is overloaded with them I absolutely despise mmc! wilma Simpson
I know that this program can be used to control others on a home network without then realizing it. I would consider it non essential unless the computer is being used as part of a work group in a business setting. I have had 2 computers crash and had some indiscriminate use of minor's computers in my household to dump files that were mostly pornographic Kathy Oddie
Keeps running 40-60%, slowing system down. smith

It is used to host .msc snap-ins such as Computer Management, Event Viewer, Services etc. It can be found in C:\Windows\system32.
