While the error has many discussions I suggest you look at AUTORUNS and learn all about your PC to correct this. That is, it's your Personal Computer and not an appliance. I know this may upset some but we control it all and can choose to dive it or take it into the shop.
Armed with tools like HIJACKTHIS and AUTORUNS I can look over each line in the HIJACKTHIS report and find out what runs at startup. I can remove items or disable them (how is all over the web) as a test. Then I can remove the item that is failing.
There's a lot of malware that can cause that so if you find such, ask your antivirus maker why they allowed this to infect your PC. I think that's a good question today. It's not as if they didn't have over a decade to get it working right.
