Description

The Remove-GPPrefRegistryValue cmdlet removes one or more Registry preference items from either Computer Configuration or User Configuration in a GPO. You must specify the Context parameter for the User or Computer to indicate whether to remove the Registry preference item from Computer Configuration or User Configuration. You can specify the GPO by its display name or by its GUID.

You can specify either a key or a value:

If you specify a key, all Registry preference items that configure that registry key or any of its first-level values are removed from the specified configuration in the GPO. Registry preference items that configure subkeys of that key or their values are not affected. For a key, specify the Key parameter without the ValueName parameter.
If you specify a value, all Registry preference items that configure that registry value are removed from the specified configuration in the GPO. For a value, specify the Key parameter without the ValueName parameter.

This cmdlet can take input from the pipeline:

You can pipe GPO objects to this cmdlet to remove a specified Registry preference item from one or more GPOs.
You can pipe PreferencRegistrySetting objects to this cmdlet to remove one or more Registry preference items from a specified GPO.

WmiFilter        :

This command removes any Registry preference items that configure the registry value HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\ExampleKey ValueOne from User Configuration for all GPOs in the domain. It returns each GPO from which at least one Registry preference item is removed.

This cmdlet returns a non-terminating error for each GPO that does not have a Registry preference item associated with the specified registry value. In this command, these error messages are suppressed by setting the ErrorAction parameter to SilentlyContinue. For more information about the ErrorAction parameter, see about_CommonParameters.

Parameters

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:	SwitchParameter
Aliases:	cf
Position:	Named
Default value:	False
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Context

Specifies whether the Registry preference item (or items) are removed from Computer Configuration or User Configuration in the specified GPO. You must specify either User or Computer.

Type:	GpoConfiguration
Accepted values:	User, Computer
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	False
Accept wildcard characters:	False

-Domain

Specifies the domain for which this cmdlet runs the operation. You must specify the fully qualified domain name (FQDN) of the domain.

For the Remove-GPPrefRegistryValue cmdlet, the GPO from which to remove the Registry preference item or items must exist in this domain.

If you do not specify the Domain parameter, the domain of the user that is running the current session is used. (If the cmdlet is being run from a computer startup or shutdown script, the domain of the computer is used.) For more information, see the Notes section in the full Help.

If you specify a domain that is different from the domain of the user that is running the current session, a trust must exist between that domain and the domain of the user or the computer.

You can also refer to the Domain parameter by its built-in alias, DomainName. For more information, see about_Aliases.

Type:	String
Aliases:	DomainName
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-Guid

Specifies the GPO from which to remove the Registry preference item by its globally unique identifier (GUID). The GUID uniquely identifies the GPO.

You can also refer to the Guid parameter by its built-in alias, Id.

Type:	Guid
Aliases:	Id
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-Key

Specifies a registry key for which to remove one or more Registry preference items; for instance, HKCU\Control Panel\Colors.

You can specify any of the following registry hives: HKEY_CLASSES_ROOT (HKCR), HKEY_CURRENT_USER (HKCU), HKEY_LOCAL_MACHINE (HKLM), HKEY_USERS (HKU), and HKEY_CURRENT_CONFIG (HKCC). Any of these hives can be specified for Registry preference items in both Computer Configuration and User Configuration.

The Key parameter can be specified with or without the ValueName parameter:

If the ValueName parameter is specified, all Registry preference items that configure the registry value are removed.
If the ValueName parameter is not specified, all Registry preference items that configure the registry key and any of its first-level values are removed.

You can also refer to the Key parameter by its built-in alias, FullKeyPath.

Type:	String
Aliases:	FullKeyPath
Position:	Named
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-Name

Specifies the GPO from which to remove the Registry preference item by its display name.

The display name is not guaranteed to be unique in the domain. If another GPO with the same display name exists in the domain an error occurs. You can use the Guid parameter to uniquely identify a GPO.

You can also refer to the Name parameter by its built-in alias, DisplayName.

Type:	String
Aliases:	DisplayName
Position:	0
Default value:	None
Required:	True
Accept pipeline input:	True

-ValueName

Specifies the name of a registry value for which to remove all Registry preference items. If you specify the ValueName parameter, you must also specify the Key parameter.

Type:	String
Position:	Named
Default value:	None
Required:	False

Inputs

Microsoft.GroupPolicy.Gpo, Microsoft.GroupPolicy.PreferenceRegistrySetting

This cmdlet takes a GPO or a PreferenceRegistrySetting object as input. You can pipe in one or more PreferenceRegistrySetting objects to remove one or more Registry preference items from a specified GPO. You can pipe in one or more GPO objects, such as Get-GPO, to remove a specified Registry preference item from each GPO. Collections that contain GPOs from different domains are not supported.

Outputs

Microsoft.GroupPolicy.Gpo

This cmdlet returns the GPO from which the Registry preference item or items that have been removed.

Notes

You can use the Domain parameter to explicitly specify the domain for this cmdlet.

If you do not explicitly specify the domain, the cmdlet uses a default domain. The default domain is the domain that is used to access network resources by the security context under which the current session is running. This domain is typically the domain of the user that is running the session. For instance, the domain of the user who started the session by opening Windows PowerShell from the Program Files menu, or the domain of a user that is specified in a runas command. However, computer startup and shutdown scripts run under the context of the LocalSystem account. The LocalSystem account is a built-in local account, and it accesses network resources under the context of the computer account. Therefore, when this cmdlet is run from a startup or shutdown script, the default domain is the domain to which the computer is joined.
