Hay the guest account dosent reset on logout how can I make it delete all the files when they log out and reset it back to normal
I think you have to manually disable it.
If you disable it and do a Disk Cleanup it should clear out temps. As the Guest account is disabled for a reason far better and more secure would be to leave the Guest account permanently disabled and create a new Limited User account for others to use. They are easier to control and check from within an Admin level account..
