This site is for the co-ordination of the Ubuntu project(s), and not support.
For Ubuntu Support options, please have a look at https://community.ubuntu.com/t/finding-help/712
ps: I clicked menu, searched for ‘updates’ & selected 'Software & Updates’ then can see the update options for when your system checks for updates (daily, every two days … never), what to do when there are security updates, what to do when they are other updates etc…
From the title it seems the OP is more interested about a Windows 10 update which applies during the shutdown process.
Just use ubuntu.
