Purge files off your pc. You won't regret it. I cleaned up 38 gb just now by going in and deleting shit I don't need and shit that doesn't get removed by the uninstaller. I can't even imagine what other useless crap is on there that I don't even need. Have you uninstalled something recently? Go to the search bar in file explorer and check everything that could possibly have anything to do with it and just go to town. Even if you have no reason to, it is incredibly satisfying. Just remove shit.
