I have had this error on both pc I own both have Norton 2010 and belive this is the problem cause. Error 1530 user profile service reg leak from winlogon app still has reg key open unloaded now , but luckily its is the same key everytime at shutdown. How do I troubleshoot this warning or any ideas on fix? Is this something I can just ignore or could it cause more serious problems later? THANKS AGAIN!
