Request for some IT Pro tools

Hi,

I'm going to put my request in for the following:

A Disk Defragger and a Registry/System Cleaner. Two that come readily to mind are:

Auslogics Disk Defrag and CCleaner respectively. As it stands right now, when I get a ticket for a slow PC I copy the programs over from my flash drive, install them to the PC, run them and then uninstall when done (we have curious users).

Needless to say it'd be great if these apps were offered via portableapps.com and save a lot of time in maintenance!

I'm sure there are many other IT Pro tools out there that people could recommend =).
