If you got warnings there sound like there is somethign wrong. You shouldnt get any warnings. Unless you are talking about unhidding the System Files that were recommended to be hidden.
Other than that there should be no errors. I dont know if deleting the Recycle files will do anything. Do you have any programs installed like Eraser or anything like that?
