may be related to virus/trojan/ransomware if not in system32. It will be located (in vista/7) in C:\Users\Username\mggddmgd (random name); can be removed by running sysinternals Autoruns and disabling it. Gave us a lot of trouble; only guaranteed way to remove ransomware related to this file. It does not mess up shell value or run/run once registry, like other ransomware.

This file is part of Windows and is required if you want to install SQL Server or other Microsoft server software. Just because a virus has tried to disguise itself as this file doesn't mean this file is dangerous.
Win2K Process. Occurred after i switched the GPU brand and didnt unistall the old GPU driver. Permanently loaded the CPU (athlon XP 1600) to 99% every time even, every user even logged in as Admin. Vanished after uninstalling the old obsolete Drivers. - check your Hardware/driver conflicts

My company has this installed on all systems for remote management and system checking. All I know is that as a non administrator I cannot remove, disable or restart this process, yet when it runs, it chews up to 98 % CPU and basically grinds my computer to a halt.

Best practices for resolving WinMgmt issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active WinMgmt process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the WinMgmt.exe on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. 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 repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
