Gets one or more registry-based policy settings under either Computer Configuration or User Configuration in a GPO.

Syntax

Get-GPRegistryValue
   -Guid <Guid>
   -Key <String>
   [-ValueName <String>]
   [-Domain <String>]
   [-Server <String>]
   [<CommonParameters>]
Get-GPRegistryValue
   [-Name] <String>

   [-Server <String>]
   [<CommonParameters>]

Description

The Get-GPRegistryValue cmdlet retrieves one or more registry-based policy settings under either Computer Configuration or User Configuration in a Group Policy Object (GPO).

You can get registry-based policy settings for a specific registry value, or for all the registry values under a key:

  • To get the registry-based policy setting that configures a specific registry value, specify both the Key and the ValueName parameters.

  • To get all the registry-based policy settings that configure values directly under a registry key, specify the Key parameter without the ValueName parameter.

If you specify only a key, in addition to the policy settings that configure values under the key, the following first-level subkeys of the key are returned:

  • first-level subkeys that have a policy setting that configures a value.

  • first-level subkeys that have a subkey, at any level, with a policy setting that configures a value.

You can use this information to browse for registry-based policy settings.

Examples

Example 1: Get the group policy registry value from the specified key

$params = @{
    ValueName = 'ValueOne'
    Key       = 'HKEY_CURRENT_USER\Software\Policies\Microsoft\ExampleKey'
    Name      = 'TestGPO'
}
Get-GPRegistryValue @params

KeyPath     : Software\Policies\Microsoft\ExampleKey
FullKeyPath : HKEY_CURRENT_USER\Software\Policies\Microsoft\ExampleKey
Hive        : CurrentUser
PolicyState : Set
Value       : TestGPO
Type        : String
ValueName   : ValueOne
HasValue    : True

This command gets the registry-based policy setting that configures the registry value HKEY_CURRENT_USER\Software\Policies\Microsoft\ExampleKey:ValueOne from User Configuration in the GPO named TestGPO.

Example 2: Get all group policy registry values from the specified key

Get-GPRegistryValue -Name "TestGPO" -Key "HKCU\Software\Policies\Microsoft\ExampleKey"

KeyPath     : Software\Policies\Microsoft\ExampleKey
FullKeyPath : HKEY_CURRENT_USER\Software\Policies\Microsoft\ExampleKey
Hive        : CurrentUser
PolicyState : Set
Value       : TestGPO
Type        : String
ValueName   : ValueOne
HasValue    : True

KeyPath     : Software\Policies\Microsoft\ExampleKey
FullKeyPath : HKEY_CURRENT_USER\Software\Policies\Microsoft\ExampleKey
Hive        : CurrentUser
PolicyState : Delete
Value       :
Type        : String
ValueName   : ValueTwo
HasValue    : True


KeyPath     : Software\Policies\Microsoft\ExampleKey\Subkey1
FullKeyPath : HKEY_CURRENT_USER\Software\Policies\Microsoft\ExampleKey\Subkey1
Hive        : CurrentUser

KeyPath     : Software\Policies\Microsoft\ExampleKey\SubKey2
FullKeyPath : HKEY_CURRENT_USER\Software\Policies\Microsoft\ExampleKey\SubKey2
Hive        : CurrentUser

This command gets all the registry-based policy settings that configure registry values under the key HKEY_CURRENT_USER\Software\Policies\Microsoft\ExampleKey from User Configuration in the GPO named TestGPO. Subkeys of this key that have registry-based policy settings, are also returned. The second registry-based policy setting (ValueTwo) is disabled (its PolicyState property is set to Delete).

Parameters

-Domain

Specifies the domain for this cmdlet. You must specify the fully qualified domain name (FQDN) of the domain (for instance: sales.contoso.com).

For the Get-GPRegistryValue cmdlet, the GPO for which to get registry-based policy settings 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 (or, for a startup or shutdown script, the computer), a trust must exist between that domain and the domain of the user or the computer.

You can also refer to Domain 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 retrieve the registry-based policy setting 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. For more information, see about_Aliases.

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

-Key

Specifies the registry key for which this cmdlet gets the registry-based policy setting. For instance: HKLM\Software\Policies\Microsoft\Windows NT\DNSClient.

The key must be in one of the two following registry hives:

  • HKEY_LOCAL_MACHINE (HKLM) for a registry-based policy setting in Computer Configuration.

  • HKEY_CURRENT_USER (HKCU) for a registry-based policy setting in User Configuration.

You can specify:

  • The Key parameter without the ValueName parameter to get all the registry-based policy settings that configure values directly under that key.

  • The Key parameter together with the ValueName parameter to get the registry-based policy setting that configures a specific registry value.

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

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

-Name

Specifies the GPO from which this cmdlet gets the registry-based policy setting 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. For more information, see about_Aliases.

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

-Server

Specifies the name of the domain controller that this cmdlet contacts to complete the operation. You can specify either the fully qualified domain name (FQDN) or the host name.

If you do not specify the name by using the Server parameter, the primary domain controller (PDC) emulator is contacted.

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

-ValueName

Specifies the name of a registry value for which this cmdlet gets the registry-based policy setting. For instance, the registry key HKLM\Software\Policies\Microsoft\Windows NT\DNSClient can have a value with the following name: UseDomainNameDevolution. For the default value of a registry key, specify "(default)" or an empty string ("").

You must also specify the Key parameter with this parameter.

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

Inputs

Microsoft.GroupPolicy.Gpo

You can pipe a GPO for which this cmdlet gets registry-based policy settings. Collections that contain GPOs from different domains are not supported.

Outputs

Microsoft.GroupPolicy.PolicyRegistrySetting

This cmdlet returns PolicyRegistrySetting objects that represent registry-based policy settings. These objects can be piped into the following cmdlets:

  • Set-GPRegistryValue

  • Remove-GPRegistryValue

Notes

  • The hive of the registry key that you specify (HKLM or HKCU) indicates whether the registry-based policy setting is retrieved from Computer Configuration or User Configuration.

    If the specified registry key cannot be located in policy (the registry key is not configured), a corresponding error message is displayed.

    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 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.
