My list of things to do:
Clean the start-up list (I'll be rebooting a bit!)
Remove Malware
Uninstall unused programs
Clear out temporary file caches
Update drivers/codecs/plug-ins
Install useful freeware (Clamwin, Firefox, etc.)
Defragment
If the users want better performance, turn off all the default flashy UI stuff.
Lastly, I assess whether or not a RAM or video upgrade is required to extend the life of the computer for another year or two.
All of this can usually be done (on one computer) between getting home at 6pm and going to bed at 11pm. I like saving people money... even I don't take a piece of the savings.
