Remove Excess ValueNames From Reg Key

Remove undesired registry values from a registry key with RegistryPlus:

RegistryPlus Remove_Excess_Values
{
    Key = 'HKEY_LOCAL_MACHINE\SOFTWARE\Test'
    AllowedValueNames = @(
        'My Value',
        'Other Value'
    )
}

This will remove all Values from the HKEY_LOCAL_MACHINE\SOFTWARE\Test key except the two values: My Value and Other Value. This function will not recurse into subkeys.

If you're controlling those two values with Registry, be sure to supply DependsOn to be sure those Values are create before doing any deletion.

Registry Set_My_Value
{
    Key = 'HKEY_LOCAL_MACHINE\SOFTWARE\Test'
    ValueName = 'My Value'
    ValueType = 'String'
    ValueData = 'Hello World!'
}

Registry Set_Other_Value
{
    Key = 'HKEY_LOCAL_MACHINE\SOFTWARE\Test'
    ValueName = 'Other  Value'
    ValueType = 'String'
    ValueData = 'Foo Bar!'
}

RegistryPlus Remove_Excess_Values
{
    Key = 'HKEY_LOCAL_MACHINE\SOFTWARE\Test'
    AllowedValueNames = @(
        'My Value',
        'Other Value'
    )
    DependsOn = @(
        '[Registry]Set_My_Value',
        '[Registry]Set_Other_Value'
    )
}

Important

• Setting Ensure = 'Absent' will cause an error.
