ARO categories scans into 3 main areas: Registry, Junk and Security. The registry scan analyzes 13 areas of the Windows registry for errors and indentifies possible registry tweaks that can help improve PC performance. The junk scan checks ten areas of the PC for clutter, freeing up disk space by identifying and removing extraneous files that can clutter and slow down a system. It also scans and removes junk accumulated from web browsers. The baseline security scan confirms a user has up-to-date security software including antivirus, antispyware, firewall and now also checks the Windows operating system update process to confirm it is properly configured.
