Answer 1

Are you sure you can make remote WMI connections to accounts without passwords?

There are a number of things such accounts can't do (share files, remote desktop, for example). Try setting a password and see if that makes a difference.

Answer 2

You may want to check to WMI Security Settings on the Remote Windows 7 PC. Right Click Computer > Manage > Services and Applications > WMI Control > Security Tab and make sure the user account you are using has the necc permissions.

Answer 3

Maybe it's the missing 'EnablePrivileges':

scope.Options.EnablePrivileges = true;

From MSDN (ConnectionOptions.EnablePrivileges Property):

Gets or sets a value indicating whether user privileges need to be enabled for the connection operation. This property should only be used when the operation performed requires a certain user privilege to be enabled (for example, a machine restart).

Edit: If it doesn't work, try setting the ImpersonationLevel to 'Impersonate':

scope.Options.Impersonation = System.Management.ImpersonationLevel.Impersonate;

ImpersonationLevel Impersonate: Impersonate-level COM impersonation level that allows objects to use the credentials of the caller. This is the recommended impersonation level for WMI calls.
