Recently in torrent-sharing, mdm.exe can also be a Bitcoin-miner. If it is taking a LOT of resources on both the CPU and GPU, make sure to go to the file of origin and remove it and the related files in that folder.
i know my security said this program has no valid digital signature that verifies its publisher. now that sounds like a good warning to me. so if the publisher would like to relax everyone tell your programers to do it right.

The Machine Debug Manager runs as a service and is loaded when your computer starts. If you do not use your computer for debugging purposes, you can safely turn off the Machine Debug Manager.

Best practices for resolving mdm issues

A clean and tidy computer is the key requirement for avoiding problems with mdm. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
