Don’t forget Portal 2’s leftovers

Again, like I mentioned previously, after Portal 2 is successfully kicked out of your computer, you still get to manually get rid of the idle leftovers including registry entries, cache files, and temporary files, etc.

It is not that easy to precisely track down those little “pieces” since they may not be named with “Portal 2” prefix. Sometimes you need to acquire the name of relevant verified publisher first to locate the keys in Registry Editor. It is better not to go there unless you are 100% sure you have targeted the right things, because they will not return once being eliminated.
