Cleanup windows install files does just that: cleaning up already installed patches. These files are just kept so you are able to uninstall/re-install any patch when you encounter problems. But normally those install files just eat up disk-space, so no harm to remove them after installation.

That you are prompted for install new patches can be triggered by some other patch / update cycle from Microsoft. Due to dependencies (unknown to us mortals) installing 1 patch can always lead to a waterfall of additional needed patches (believe me I have been there recently after configuring a new machine). So good practice is after some update to always re-query again and again for any other patches until none are found.
