Windows 10: MpCmdRun.exe Failing When Run as SYSTEM User

I am running a Windows Defender scan with the Microsoft utility MpCmdRun.exe. I am using this command:


MpCmdRun.exe -scan -scanType 1


This runs just fine when I am a Local Administrator. When I run it as the SYSTEM user it will work once and then will fail on every subsequent run. If I reboot my machine it will once again run once and then fail every other time.


Any clues as to what might be going on and how I might fix this?

Hi Brian,

The MpCmdRun.exe is associated with the Windows Defender program and is located in
C:\Program Files\Windows Defender. There are malicious programs that uses the same name so you won't suspect that it is malware. To check if this process is a malicious program, you can follow these steps:

• Right-click Start and select Task Manager.
• Under the Process tab, locate the MpCmdRun.
• Right-click MpCmdRun and select Open file location.

If the location is C:\Program Files\Windows Defender, then the system is safe and secure. If the location is elsewhere then we suggest that you run a virus and malware scan on your computer.

Let us know if you have any other questions.
