MMC is Microsoft Management Console, a core part of the Windows operating system. It is used to host .msc snap-ins such as Computer Management, Event Viewer, Services etc. It can be found in C:\Windows\system32. On 64 bit Windows there is also a 32 bit version in C:\Windows\syswow64.

Keeps running 40-60%, slowing system down.

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

Best practices for resolving mmc issues

A clean and tidy computer is the key requirement for avoiding problems with mmc. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the mmc.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
