If you mess with group policy a little you'd know where the files are. Right click then "location" shows the directory. In "This PC" all the links are shortcuts. Profile issues are very common, that's why companies keep them in network locations (roaming, desktop, other folders). And for the network location, daily backups (or hourly depending on the setting) then roll version backup for disasters. Also, don't use 14 years old EOL systems.
