start looking at "portable applications" there are plenty available. the beauty of portable applications, is that the registry is not affected. watso runs a whole lot of portable applications from an external usb drive. a good starting point is the lupo bundle of software

which contain 200 programs - just download that one lot - because all 200 programs are in there , and include all a multitude of browsers, media players etc etc etc. indeed, there are a whole lot of nifty little programs, that you might only use every so now and then - but they are still handy to have. the beauty is that they can all be run externally, and can be carried around on a usb flash drive, and taken from computer to computer - eg, your portable browser can have all of your history, bookmarks , passwords etc - and you can simply take them from computer to computer - well worth looking at
