The Win32_NTLogEventComputer association WMI class relates a computer and an event.
Methods
Win32_NTLogEventComputer has no methods.
Properties
Win32_NTLogEventComputer returns 2 properties:
'Computer','Record'
Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:
Get-CimInstance -ClassName Win32_NTLogEventComputer -Property *
Most WMI classes return one or more instances.
When
Get-CimInstance
returns no result, then apparently no instances of class Win32_NTLogEventComputer 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).
Computer
KEY PROPERTY WIN32_COMPUTERSYSTEM
Reference to the instance on which this event occurred.
Get-CimInstance -ClassName Win32_NTLogEventComputer | Select-Object -Property Computer, Record
Record
Reference to the instance representing the event.
Get-CimInstance -ClassName Win32_NTLogEventComputer | Select-Object -Property Computer, Record

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 = 'Computer',
'Record'
Get-CimInstance -ClassName Win32_NTLogEventComputer | 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_NTLogEventComputer -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_NTLogEventComputer -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 Computer, Record FROM Win32_NTLogEventComputer 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 Computer, Record FROM Win32_NTLogEventComputer WHERE Caption LIKE 'a%'" | Select-Object -Property Computer, Record
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_NTLogEventComputer -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_NTLogEventComputer -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_NTLogEventComputer, 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_NTLogEventComputer was introduced on clients with Windows XP and on servers with Windows Server 2003.
Namespace
Win32_NTLogEventComputer 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_NTLogEventComputer is implemented in Ntevt.dll and defined in Ntevt.mof. Both files are located in the folder C:\Windows\system32\wbem
:
explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\Ntevt.mof
