Using Windows Vista on a Compaq Presario CQ50 laptop. I continually get the message that Windoes can't check for updates. I have searched the INternet for a solution and have checked the registry for the entries mentioned that could be related to this problem but they don't exist in my registry. There error code I am getting is 80070005. I have heard that Windows Live Messenger can have something to do with this error. Please advise.
