win 7 home premium 64 bit

Just getting rid of the useless microsoft games folder, I am told I do not
have permission to delete the png images. Everything else deletes.
So I go to set permissions. Nope. Can't do that either. It will not change
from "creator owner".

I change ownership, go through the hoops, click ok. All appears to be fine.
But nope. Windows is saying **** you. We're not allowing you to make the
damn changes on this. You're stuck with it.

It's my god damned ****ing machine! If I don't want your crap on it then
that is my right. What the hell is so damned privileged about a frickin
image?

Now how do I fix it?
