it is the feature behind and I recommend, like @willisxdc , each user to disable this quick start feature. ( My Thoughts on CTD's - #10 by MichaMMA )
Beside of this, to be sure, made sometime a Restart.. because you are right: in Windows 10 is shutdown and restart not the same.
Users can simple check when a real ‘restart’ was made with help of the task-managers “up time”:
If a strange high value is shown and not the time which is gone since PC was started, then users not made a real restart.
EDIT: replaced Reboot with the word Restart, so that it better match what @Riverrover mentioned
=> but meant is/was with Reboot of course that Restart: the Windows → Restart Button. About that I wrote.
