How can I view web sites visited and temp internet files when the history and th files have been deleted?

You really can't once they are deleted if a system restore does not work

Easy and quick way to restore file and activity History is the System Restore feature. Since much history is saved into the Windows Registry, restoring it to a previous state will restore file and program History.

* Choose a date you would like the computer reverted to


Just go down to where it says - Use System Restore
