Question: I want to install a game on my computer (the sims) but it takes up a lot of memory. If I install it, and then uninstall it later in time, will all the memory it used be freed up?
Answer: Provided that the uninstall process is written properly it should uninstall everything and free up all of the space. There are some improperly written uninstall processes that leave things behind. If that happens then the only option would be to clean the remainer up manually.
