Anyway, as first it's needed to define, what exactly you mean with "hide defered updates"? Here is the situation, that is happeneing when using TVSU: - once you start TVSU and defer, or update your system using some updates, then these updates are stored and downloaded to following direction: %programfiles%\Lenovo\System Update\session There you surelly see multiple folders, that are the same, as the name of the update package.
Ok, now you downoad an update with the defered option. So what happens is that this file is downloaded into this location. Now if you forget to install this deffered update and in meantime a new version of this particular update will be released, then you can start TVSU and again deffer this same update (but with newer version). In this situation, the old version will be no longer seen and you will have only the latest version visible, BUT the older version will not be deleted. It will still reside in the above mentioned location.
