If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

If the implementer does not care about the state of a given pane and therefore does not want to change it, then the implementer should return a success code for the method and EPS_DONTCARE for the peps parameter. If the method fails, it is treated as if EPS_DONTCARE was returned for the peps parameter.
