Why would one not choose to be as thorough as possible? Is there a danger in being "too thorough," a chance of removing something not associated with the program you want to uninstall? Or is Revo absolutely certain that everything it gives you a choice about was actually created for the program to run?

The perfection is not of this world. There always is a margin for errors, even for a well written program. What Revo does is to forbid you to delete things that it is sure do not belong to the program being uninstalled. It marks as deletable all what potentially belongs to that program. Then you have to apply your own judgment to remove the "delete this" flag from the items you recognize as being erroneously flagged. All of this imply a certain knowledge of how the registry is structured, and what the main entries are. If this scares you, then Revo is not the program for you. Uninstalling errant programs is more of an art than a science, and some sort of cooperation from the user is needed. But if you know what you are doing, Revo is a powerful tool in your hands.

I just looked up Revo Uninstaller Pro and apparently it starts by running a program's regular uninstaller. But they don't say what happens if the regular installer abnormally terminates.

Yes, that is what it does initially. Then, after the termination, normal or abnormal, of the regular uninstaller, it starts a thorough scan (you can choose how thorough it must be) of the registry, finding all the remnants of the just "uninstalled" program, including the registry entries used by the Windows uninstaller. Then you have the choice of selecting which entries you want to delete. Usually this frees completely the PC from any traces of the program you want to get rid of. In my case, it saved my a.. many times :) Good luck !

Thanks God it does exist Revo Uninstaller Pro... I routinely use it to wipe out whatever traces a program that I want to completely uninstall tries to left behind itself, either in the registry or in configuration files.... It saved me many problems many times....
