mdm is an abbreviation of Machine Debugger Manager. The process is not harmful actually, but sometimes it may be dangerous for those who have installed graphics card in their systems. The process begins whenever operating system starts, which is used by the Windows NT Option Pack and Microsoft Developer Studio to provide application debugging. It's not essential, but it can reserve up to 38% processing speed while running computer. As I said, it's really harmful for those who have graphics card because when this process starts then GPU temperature increases without gaming or playing games. So in this situation, if you start a game then your GPU may be burn due to high temperature. That's why we should close this process. Otherwise, something else may have happened wrong.
Is This Process A Virus?While searching about mdm process, I saw different users who were asking a very common question "Is this process a virus?" Actually, it's not a virus. It enables due to the internet explorer Script Debugging. It means, the process directly links with it. But it may be harmful for those who have graphics card. Because I've said it already, when this process starts then GPU temperature increases up to 75-78°C. So in this situation, when you'll start a game as well then your GPU may be burn. That's all!
