Explanation
The behavior described - a JPEG opening a command prompt - indicates that the file extension association for .jpg/.jpeg has been hijacked or altered, a common malware technique. The 'Folder Options' Control Panel utility (under 'File Types' or via File Explorer options) allows a technician to view and correct file extension associations, restoring .jpg files to open with an image viewer. Display Settings, Device Manager, and Internet Options do not manage file type associations.
