All I have on start up is my security programs .being a laptop you may need to keep a few others as well.
Go into clean up and run that and it will also show you how much disk space he has left.
Make sure his Security programs are not running scans at start up.Time them to run at different times.
Looks like running c Cleaner might help as well.
Check in device manager to see if any yellow exclamation marks beside any of the drivers.
Maybe help others if you let us know what operating system he is using.
