Your goal with the Belarc Advisor is to ensure that your system is completely up tp date. That is the function of windows update. Until your system is completely updated you will have serious security weaknesses. On the right side of the report it tells you whether your system is up to date. If not,then click on the section to find what updates are missing. These will have to be installed manually from the standalone installs on Microsoft.com. Some updates may be dependent on another update being installed. If you have many updates which keep failing in your update history then this is a sign that something is drastically wrong with windows update and a repair install would be in order. Please provide us with a copy of your Belarc Advisor to determine the next step.
