Swindon maintained their 100% start to the season under new boss Dennis Wise after beating struggling Stockport.
Aaron Brown's left-footed free-kick gave Swindon the lead, with winger Ricky Shakes almost getting a second with a dipping strike that hit the bar.
Welshman Christian Roberts was also unlucky just after the hour when his half-volley was deflected wide of the upright by Ashley Williams.
Soon after Roberts cleverly sneaked a shot past keeper James Spencer.
