DESCRIPTION
The Get-WmiObject cmdlet gets instances of WMI classes or information about the available WMI classes. The Computer
Name parameter can always be used to specify a remote computer. If the List parameter is specified, the cmdlet get
s information about the WMI classes that are available in a specified namespace. If the Query parameter is specifie
d, the cmdlet runs a WMI query language (WQL) statement.

The Get-WmiObject cmdlet does not use the Windows PowerShell remoting infrastructure to perform remote operations.
You can use the ComputerName parameter of the Get-WmiObject cmdlet even if your computer does not meet the requirem
ents for Windows PowerShell remoting and even if your computer is not configured for remoting in Windows PowerShell
.


PARAMETERS
-Amended []
Gets or sets a value that indicates whether the objects that are returned from WMI should contain amended infor
mation. Typically, amended information is localizable information, such as object and property descriptions, th
at is attached to the WMI object..

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-AsJob []
Runs the command as a background job. Use this parameter to run commands that take a long time to finish.

When you use the AsJob parameter, the command returns an object that represents the background job and then dis
plays the command prompt. You can continue to work in the session while the job finishes. If Get-WmiObject is u
sed against a remote computer, the job is created on the local computer, and the results from remote computers
are automatically returned to the local computer. To manage the job, use the cmdlets that contain the Job noun
(the Job cmdlets). To get the job results, use the Receive-Job cmdlet.

Note: To use this parameter with remote computers, the local and remote computers must be configured for remoti
ng. Additionally, you must start Windows PowerShell by using the "Run as administrator" option in Windows Vista
and later versions of Windows,. For more information, see about_Remote_Requirements.

For more information about Windows PowerShell background jobs, see about_Jobs and about_Remote_Jobs.

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-Authentication
Specifies the authentication level to be used with the WMI connection. Valid values are:

-1: Unchanged
0: Default
1: None (No authentication in performed.)
2: Connect (Authentication is performed only when the client establishes a relationship with the application.)
3: Call (Authentication is performed only at the beginning of each call when the application receives the reque
st.)
4: Packet (Authentication is performed on all the data that is received from the client.)
5: PacketIntegrity (All the data that is transferred between the client and the application is authenticated a
nd verified.)
6: PacketPrivacy (The properties of the other authentication levels are used, and all the data is encrypted.)

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-Authority
Specifies the authority to use to authenticate the WMI connection. You can specify standard NTLM or Kerberos au
thentication. To use NTLM, set the authority setting to ntlmdomain:, where identifies
a valid NTLM domain name. To use Kerberos, specify kerberos:\". You cannot include the
authority setting when you connect to the local computer.

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-Class
Specifies the name of a WMI class. When this parameter is used, the cmdlet retrieves instances of the WMI class
.

Required? false
Position? 2
Default value
Accept pipeline input? false
Accept wildcard characters? false

-ComputerName
Specifies the computer against which you want to run the management operation. The value can be a fully qualifi
ed domain name, a NetBIOS name, or an IP address. Use the local computer name, use localhost, or use a dot (.)
to specify the local computer. The local computer is the default. When the remote computer is in a different do
main from the user, you must use a fully qualified domain name. This parameter can also be piped to the cmdlet.

This parameter does not rely on Windows PowerShell remoting, which uses WS-Management ). You can use the Comput
erName parameter of Get-WmiObject even if your computer is not configured to run WS-Management remote commands.

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-Credential
Specifies a user account that has permission to perform this action. The default is the current user. Type a us
er name, such as "User01", "Domain01\User01", or User@Contoso.com. Or, enter a PSCredential object, such as an
object that is returned by the Get-Credential cmdlet. When you type a user name, you will be prompted for a pas
sword.

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-DirectRead []
Specifies whether direct access to the WMI provider is requested for the specified class without any regard to
its base class or to its derived classes.

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-EnableAllPrivileges []
Enables all the privileges of the current user before the command makes the WMI call.

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-Filter
Specifies a Where clause to use as a filter. Uses the syntax of the WMI Query Language (WQL).

Important: Do not include the Where keyword in the value of the parameter. For example, the following commands
return only the logical disks that where the DeviceID equals 'c:' and the services where the name equals 'WinRM
', without using the Where keyword:

get-WmiObject Win32_LogicalDisk -filter "DeviceID = 'c:' "
get-wmiobject win32_service -filter "name='WinRM'"

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-Impersonation
Specifies the impersonation level to use. Valid values are:

0: Default (reads the local registry for the default impersonation level , which is usually set to "3: Imperson
ate".)
1: Anonymous (Hides the credentials of the caller.)
2: Identify (Allows objects to query the credentials of the caller.)
3: Impersonate (Allows objects to use the credentials of the caller.)
4: Delegate (Allows objects to permit other objects to use the credentials of the caller.)

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-List []
Specifies whether to retrieve and display the names of the WMI classes in the WMI repository namespace that is
specified in the Namespace parameter. The Default Namespace registry entry in the HKEY_LOCAL_MACHINE\SOFTWARE\
Microsoft\WBEM\Scripting registry key is not used by this cmdlet to determine the default namespace. If you spe
cify the List parameter but not the Namespace parameter, the root\CIMV2 namespace is used by default.

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-Locale
Specifies the preferred locale for WMI objects. Specify the value of the Locale parameter as an array in the MS
_ format in the preferred order .

WMI class is located. When used with the List parameter, it specifies the namespace from which to gather WMI cl
ass information.

Required? false
Position? named
Default value
Accept pipeline input? false
Accept wildcard characters? false

-Property
Specifies the WMI class property or set of properties to retrieve.

Required? false

This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer and OutVariable. For more information, type,
"get-help about_commonparameters".

INPUTS
None
You cannot pipe input to Get-WmiObject.


OUTPUTS
PSObject or System.Management.Automation.RemotingJob
When you use the AsJob parameter, the cmdlet returns a job object. Otherwise, the object that Get-WmiObject ret
urns depends on the value of the Class parameter.


NOTES


To access WMI information on a remote computer, the cmdlet must run under an account that is a member of the lo
cal administrators group on the remote computer. Alternatively, the default access control on the WMI namespace
of the remote repository can be changed to give other account access rights.

By default, only some of the properties of a WMI class are displayed. The set of properties that will be displa
yed for each WMI class is specified in the Types.ps1xml configuration file. One of the examples included in thi
s Help topic demonstrates how to override this behavior by using the Format-List cmdlet.
