Scans and user account status

Just curious ( curiosity raised by another post) how the user account status ( admin account vs limited account) effects the scanning options
If I understand correctly a manual scan( quick or full scan) is different as to what files are accessed based on the user account initiating the scan.
But what about:
Scheduled full system scan
The quick scans that happen after a new virus defs are obtained ? Do they scan the same files regardless if the logged in user account?
So if I’m logged in as a limited user and a scheduled full system scan runs during that time, does it scan the same files as it would if I was logged in as admin account? Same for the quick scans that happen after def set update?
