Some softwares hide their uninstall entry such that it doesn't appear under add/remove programs. It is still possible to uninstall them by using a third party application that looks for ALL installed software, even if hidden. Many total uninstallers create their logs from running during the initial install, thus have problems removing software that was installed prior to this. Installing the same version over the top of the original whilst running the uninstall logger will create a log that should enable a complete removal.
Sometimes, the uninstall via add/remove programs gets corrupted, and even if listed, will give an "unable to uninstall" error.
There are a number of Microsoft components that come with "this cannot be removed once installed" in the notes, so it IS possible to create software that cannot be removed. If Titan have done this deliberately, then they should be considered for the "rogue software" section of CM. It is more likely though that this has happened by accident, else there would have been a flood of complaints from players unable to remove the software.
CCleaner comes with it's own uninstall tool, as does Advanced System Care. TweakUI from Microsoft also offers similar functionality.
When an installer installs software, it creates a log of what it does, and stores a link to this in the registry. This is where add/remove programs looks when generating it's list. It is possible to hide this entry from add/remove programs by storing the details in a registry key not inspected by add/remove programs, or by recording a "null" string for the software display name such that add/remove programs thinks there is nothing there to list.
