Client/game updates

@Riot can you please make it so that your updates delete old registry entries for Windows? Every single time I have an update it creates 1 or several registry errors that I then have to clear out with CCleaner in order for my client to not give errors, fail to launch, etc. This is a minor inconvenience but one that has persisted throughout the life of this game. It would be quite nice if there was a fix for this. And I don't mean validating game files, that doesn't solve it as the nature of the problem is any update to the game you guys push out whatsoever. Thank you.
