Without doing a clean install, not really.
You can clean things up a bit, but not like new. First I'd run disk cleanup, and click on the Clean up system files option. Select every checkbox and click ok. Let it run. It will take a while.

And then follow these instructions, on doing a clean install if you decide to do that. Be aware that doing a clean install will wipe out anything currently on that drive, so back up any important information on it first.
