Lansweeper cannot tell you which fixes are missing from a machine, if this is what you're referring to. It only scans hotfixes that are already installed. This information is pulled from the Win32_QuickFixEngineering WMI (Windows Management Instrumentation) class. More info on this class can be found
here.
You can list installed hotfixes by following the instructions in our previous post. This information is also listed in the Config/Windows/Quickfix section of individual computer webpages.
