Automation of disk prep for backup

I would like to prepare my system disk for backup by running CCleaner, followed Windows Update and then Defraggler. I would like to make a script file so that with "One Click" I could run them one after another and my disk made ready for Backup. Can someone help me configure CCleaner so it would run start to finish without needing any manual intervention.

sounds like the /AUTO switch is what you need.
