Get-MpComputerStatus returns no output

Occasional Visitor



on a Server 2019 with windows defender installed in the "Windows Security GUI" all is fine.

Protection definitions are up to date, exclusions are set ... (managed with SCCM)


But when i use the Get-MpComputerStatus it returns no output. (not even an error)


Please help.

I'm having the same issue. Did you get this resolved?

When you run the command 

what do you see in the Windows Event Log 

Application and Services Log \ Microsoft \ Windows \ PowerShell \Operational



Im also experiencing this issue. no output from Get-MpComputerStatus or Get-MpPreference,


nothing logged to Microsoft\Windows\PowerShell\Operational when running the commands


If you Right-Click on it, can you click on Enable Logging?

@farismalaeb logging is enabled already for that log, just that when running the PowerShell commands nothing is logged the event viewer


Run the following command

Get-CimInstance -ClassName MSFT_MpComputerStatus -Namespace root/microsoft/windows/defender 

There are no entries in that log when I execute any of the Get-Mp* commands.
There is no output when I query that WMI namespace and class. I also tried Get-WmiObject -Namespace root\Microsoft\protectionmanagement -Class MSFT_MpComputerStatus which also had no output.



Here is a screenshot.

Is Windows Defender registered and working fine, 

is it Enabled or there is a policy which disables it ?!
