In my opinion it would be a good idea to notice only critical Windows Updates, which are actually missing.
Or maybe the user should decide with options panel what kind of Windows Updates should be checked by System Analyzer? For example, as I know, it's not quite necessary to monitor for an optional updates (e.g. additional Windows services, hardware drivers), while the most important parts are generally critical updates for Windows security and it's vulnerability.
Of course it's only my little suggestion, just a single thought, which may be refused, but I would like to know what do you think about this?:D
