Win32_ProcessStopTrace - powershell.one

The Win32_ProcessStopTrace event WMI class indicates that a process is terminated.

Methods

Win32_ProcessStopTrace has no methods.

Properties

Win32_ProcessStopTrace returns 8 properties:

'ExitStatus','ParentProcessID','ProcessID','ProcessName','SECURITY_DESCRIPTOR',
'SessionID','Sid','TIME_CREATED'

Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:

Get-CimInstance -ClassName Win32_ProcessStopTrace -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class Win32_ProcessStopTrace exist. This is normal behavior.

Either the class is not implemented on your system (may be deprecated or due to missing drivers, i.e. CIM_VideoControllerResolution), or there are simply no physical representations of this class currently available (i.e. Win32_TapeDrive).

ExitStatus

UINT32

Exit status of the stopped process.

Get-CimInstance -ClassName Win32_ProcessStopTrace | Select-Object -Property ExitStatus

ParentProcessID

UINT32

Process that starts an event.

Get-CimInstance -ClassName Win32_ProcessStopTrace | Select-Object -Property ParentProcessID

ProcessID

UINT32

The ProcessID property identifies the process involved in the event.

Get-CimInstance -ClassName Win32_ProcessStopTrace | Select-Object -Property ProcessID

ProcessName

STRING

Name of the process that stops. You can use this name to get the instance of Win32_Process for the same process.

Get-CimInstance -ClassName Win32_ProcessStopTrace | Select-Object -Property ProcessName

SECURITY_DESCRIPTOR

UINT8 ARRAY

Get-CimInstance -ClassName Win32_ProcessStopTrace | Select-Object -Property SECURITY_DESCRIPTOR

SessionID

UINT32

Session under which the process exists.

Get-CimInstance -ClassName Win32_ProcessStopTrace | Select-Object -Property SessionID

Sid

UINT8 ARRAY

The Sid property is the security identifier representing the user context under which the event happened.

Get-CimInstance -ClassName Win32_ProcessStopTrace | Select-Object -Property Sid

TIME_CREATED

UINT64

For more information about using uint64 values in scripts, see Scripting in WMI.

Get-CimInstance -ClassName Win32_ProcessStopTrace | Select-Object -Property TIME_CREATED

Selecting Properties

To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.

Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.

Selecting Properties

The code below lists all available properties. Remove the ones you do not need:

$properties = 'ExitStatus',
              'ParentProcessID',
              'ProcessID',
              'ProcessName',
              'SECURITY_DESCRIPTOR',
              'SessionID',
              'Sid',
              'TIME_CREATED'
Get-CimInstance -ClassName Win32_ProcessStopTrace | Select-Object -Property $properties

Limiting Network Bandwidth

If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:

Get-CimInstance -Class Win32_ProcessStopTrace -Property $property | 
Select-Object -Property $property

Selecting Instances

To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).

The parameter -Filter runs a simple query.

Listing all instances where the property Caption starts with “A”

Get-CimInstance -Class Win32_ProcessStopTrace -Filter 'Caption LIKE "a%"' 

Using a WQL Query

The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:

Get-CimInstance -Query "SELECT ExitStatus, SessionID, SECURITY_DESCRIPTOR, ParentProcessID FROM Win32_ProcessStopTrace WHERE Caption LIKE 'a%'"

Any property you did not specify is still present but empty. You might need to use Select-Object to remove all unwanted properties:
Get-CimInstance -Query "SELECT ExitStatus, SessionID, SECURITY_DESCRIPTOR, ParentProcessID FROM Win32_ProcessStopTrace WHERE Caption LIKE 'a%'" | Select-Object -Property ExitStatus, SessionID, SECURITY_DESCRIPTOR, ParentProcessID

Accessing Remote Computers

To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.

Authenticating as Current User

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with your current identity:
$result = Get-CimInstance -ClassName Win32_ProcessStopTrace -ComputerName $list 
$result

Authenticating as Different User

Use a CIMSession object to authenticate with a new identity:

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred

$result = Get-CimInstance Win32_ProcessStopTrace -CimSession $session

# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session

$result

Requirements

To use Win32_ProcessStopTrace, the following requirements apply:

PowerShell

Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.

If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.

Operating System

Win32_ProcessStopTrace was introduced on clients with Windows Vista and on servers with Windows Server 2008.

Namespace

Win32_ProcessStopTrace lives in the Namespace Root/CIMV2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance.

Implementation

Win32_ProcessStopTrace is implemented in Krnlprov.dll and defined in Krnlprov.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\Krnlprov.mof
