Help me create my USB drive with tools, tech bench!

Currently on my flash stick, I keep folders, subfolders of machines ex. HP, Dell, then another folder Dimension 2400 and list all the drivers for the machine so my work ca be done quicker.

I like to add some tools, what are some must tools, only tool I have right now is CPU-z.

Sometimes I have to work on PC's which only have Windows and Office.
So I have two Flash memory sticks with useful portable programs installed.
One has 'PortableApps' program launcher with many programs converted to portable use by John T. Haller;~

Use the pop-up menu, and it's options, to add the programs you require.

On my other stick I have, 'Codysafe', a similar idea. See;~

*I use Firefox 2 portable, CCleaner portable, Recuva, Abiword portable, Auslogics Defrag and many others. All the portable programs run on either 'Launcher'.
