IObit Uninstaller also offers an interesting feature called Forced Uninstall, for applications that cannot be removed via their own uninstallers. I tried this with an application that did have a registered uninstaller, and IObit Uninstaller correctly detected and ran it, rather than forcibly remove it. I then used it to remove a simple portable application that didn't come with an installer (or uninstaller, for that matter). IObit Uninstaller deleted the portable application smoothly and without a hitch.

After completing the uninstall process, IObit Uninstaller lets you run a Powerful Scan (their capitalization, not mine), which runs through the hard drive and registry, looking for anything the uninstaller may have left behind. The results are then shown as a tree of files and registry entries which you can manually mark for deletion--a responsible choice, since IObit won't automatically delete anything for you.

If you're happy with the uninstaller built into Windows, you may feel right at home with IObit Uninstaller. The Forced Uninstall and Powerful Scan features can help uncover leftovers that would otherwise remain hidden. But if you're serious about application removal, you may want to check out Revo Uninstaller Pro after all.
