RegistryPolicyFile: Conflicting Key When Setting Same Policy For Multiple Target Types

[pyrostew]

Details of the scenario you tried and the problem that is occurring

I am trying to set the same user configuration policy for all users of the PC however there is no target type for "All Users" and because the target type is not a Key parameter there can't be multiple instances of the resource with the same parameters named "Key" and "ValueName".

Verbose logs showing the problem

This is the error message:

PSDesiredStateConfiguration\Configuration : A conflict was detected between resources '[RegistryPolicyFile]SetDesktopWallpaperPathForAdmin (C:\Agent-1\_work\4\s\Package Builders\Win10BaseConfig\Config.ps1::164::7::RegistryPolicyFile)' and '[RegistryPolicyFile]SetDesktopWallpaperPath (C:\Agent-1\_work\4\s\Package Builders\Win10BaseConfig\Config.ps1::182::7::RegistryPolicyFile)' in node 'localhost'. Resources have identical key properties but there are differences in the following non-key properties: 'TargetType'. Values 'Administrators' don't match values 'NonAdministrators'. Please update these property values so that they are identical in both cases.

Suggested solution to the issue

Either add a target type that can add a policy for all users Update Target Type to be one of the Key parameters Update the Account Name Parameter to take an array of users and groups.

The DSC configuration that is used to reproduce the issue (as detailed as possible)

RegistryPolicyFile SetDesktopWallpaperStyle
{
  Key         = "Software\Microsoft\Windows\CurrentVersion\Policies\System"
  TargetType  = 'Administrators'
  ValueName   = "WallpaperStyle"
  ValueType   = 'Dword'
  ValueData   = "0"
}

RegistryPolicyFile SetDesktopWallpaperStyle
{
  Key         = "Software\Microsoft\Windows\CurrentVersion\Policies\System"
  TargetType  = 'NonAdministrators'
  ValueName   = "WallpaperStyle"
  ValueType   = 'Dword'
  ValueData   = "0"
}
