Use Windows Add/Remove programs or application packaged uninstaller?

Please tell me which way is better that will leave no residue and junk in my PC. Thanks.

Most of the common programs can be removed by the Add/Remove programs. We will need it when a program without an uninstall file. But some commercial programs have their own technology, which makes it unique. So the programs can not be removed by Add/Remove programs completely. If you use Add/Remove programs to deal with every program, it is obvious there are residue and junk left in you PC. In this case, you’d better use uninstaller included in the application. We come to a conclusion that we should use both of them to complement each other. What’s more, use one more dedicated program to clear up the broken registry keys left.
