Win32_LoadOrderGroup - powershell.one

The Win32_LoadOrderGroup WMI class represents a group of system services that define execution dependencies. The services must be initiated in the order specified by the Load Order Group, as the services are dependent on each other. These dependent services require the presence of the antecedent services to function correctly. The data in this class is derived by the provider from the registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ServiceGroupOrder.

Methods

Win32_LoadOrderGroup has no methods.

Properties

Win32_LoadOrderGroup returns 7 properties:

'Caption','Description','DriverEnabled','GroupOrder','InstallDate','Name','Status'

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

Get-CimInstance -ClassName Win32_LoadOrderGroup -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class Win32_LoadOrderGroup 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).

Caption

STRING MAX 64 CHAR

A short textual description of the object.

Get-CimInstance -ClassName Win32_LoadOrderGroup | Select-Object -Property Name, Caption

Description

STRING

A textual description of the object.

Get-CimInstance -ClassName Win32_LoadOrderGroup | Select-Object -Property Name, Description

DriverEnabled

BOOLEAN

Indicates whether this load order group can include drivers along with system services.

Get-CimInstance -ClassName Win32_LoadOrderGroup | Select-Object -Property Name, DriverEnabled

GroupOrder

UINT32

Sequence in which this group of services is loaded onto the operating system.

Example: 2

Get-CimInstance -ClassName Win32_LoadOrderGroup | Select-Object -Property Name, GroupOrder

InstallDate

DATETIME

Indicates when the object was installed. Lack of a value does not indicate that the object is not installed.

Get-CimInstance -ClassName Win32_LoadOrderGroup | Select-Object -Property Name, InstallDate

Name

KEY PROPERTY STRING

Name of the load order group.

Example: “Primary disk”

Get-CimInstance -ClassName Win32_LoadOrderGroup | Select-Object -Property Name

Status

STRING MAX 10 CHAR

Current status of an object. Various operational and nonoperational statuses can be defined. Available values:

$values = 'Degraded','Error','Lost Comm','No Contact','NonRecover','OK','Pred Fail','Service','Starting','Stopping','Stressed','Unknown'

Get-CimInstance -ClassName Win32_LoadOrderGroup | Select-Object -Property Name, Status

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 = 'Caption',
              'Description',
              'DriverEnabled',
              'GroupOrder',
              'InstallDate',
              'Name',
              'Status'
Get-CimInstance -ClassName Win32_LoadOrderGroup | 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_LoadOrderGroup -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_LoadOrderGroup -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 InstallDate, Caption, Status, DriverEnabled FROM Win32_LoadOrderGroup 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 InstallDate, Caption, Status, DriverEnabled FROM Win32_LoadOrderGroup WHERE Caption LIKE 'a%'" | Select-Object -Property InstallDate, Caption, Status, DriverEnabled

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_LoadOrderGroup -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_LoadOrderGroup -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_LoadOrderGroup, 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_LoadOrderGroup was introduced on clients with Windows Vista and on servers with Windows Server 2008.

Namespace

Win32_LoadOrderGroup 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_LoadOrderGroup is implemented in CIMWin32.dll and defined in CIMWin32.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\CIMWin32.mof
