I think you will find Windows comes with a backup utility that allows you to set up an automatic set of files and folders to include in any later backup and then when it is carrying out the update it will only update any changed or additional files.

Which specific folders you choose is of course up to you but I always include my "Downloads", "Utilities" & "Drivers" folders as they contain all the bits n bobs I would need should I every be forced to do a reinstall.

These discs are great for helping others too as when I am setting up a new system I always have a couple of CD's containing all the most useful little programs easily to hand.
