Windows Cleaner Updater is the software updater program which runs in the background of Windows and automatically starts up when your PC boots. It checks for software udpates and automatically downloads and installs them if found. The updater will check for updates remotely and install them based on an internal schedule.

autoupdate.exe is an auto-starting process that used the Windows Task Scheduler service to load when the user logs into Windows (sometimes this is required to bypass the UAC protection). This is typically installed with the program Windows Cleaner published by VTools and is most likely removed by most users once installed (58% removed).
