If you want to view your computer's firewall, press Windows + R > Type firewall.cpl or wf.msc.
Regarding storage, you must have performed a system restore while keeping your files. When a system restore is performed, Windows comes with an updated build, so you don't see which updates have already been installed, as they are integrated into the installation.
If you want to reduce space, see what is consuming storage and delete it. Open Windows settings > System > Storage.
