Need To Know What a Software Program Touches When it Runs?

Dependency Walker is a great program to debug problems on your PC. If you get an error message when you are running an application, pull it up in Dependency Walker and you'll see what it is accessing and if it has a problem with any of the stuff it is using to get up and running. It can also be useful for deciding if you are going to delete things off your computer. This is a program that you install and then run only when you want to take a look at something. Therefore, you don't have to worry about resources... It is a handy tool to have at your disposal and I think everyone should keep it around 'just in case'.
