I must be naive. i thought a guest account would provide some kind of safety or security, or blocking, or something from primary account. Just created one in Win 8.1, and switched user to guest. The desktop is different, slimmed down, but I can open every file, spreadsheet, financial statements, etc.
So, am I naive, or stupid or both? What am I missing? Why bother with a guest account? What good are they?
