Look in here to see if there is a shortcut to the temp file location. It may be a hidden file so make sure in the file explorer ribbion the view tab has show hidden items selected
C:\Users(User-Name)\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
While you are there you can look in all of them so see if there is a shortcut to it I would look in google to see if there is one since you said it happened more while that was in use. Maybe searching for the word "shortcut" or "temp" will give you a list.
I have found a shortcut to temp files, what do I do?
