Software Install Comparison Utility? Hi All, Is there some utility, tool, or software package that basically compares what files are on the hard drive BEFORE an installation of a software package and AFTER an install? Example: If I install AOL Instant Messenger, is there a utility out there that will tell me what directories AIM wrote to, what DLL's where loaded, what new folders were created, etc..? I remember seeing something like "WinDiff" but it looks like it's only for application level programming. Also, it would be nice if this program showed memory status of the computer before, during, and after the installation. Thanks in advance!
