Hello Pinkiestar,
I'm not sure you will be able to view the
browsing history since it was deleted, but they are storeed at the hidden
C:\Users\(User Name)\AppData\Local\Microsoft\Windows\Temporary Internet Files folder. You might be able to use the free program
Recuva to restore the files at that location to see where he was at though.
You might keep him on a Standard account instead and
setup Parental Controls on it, then enable
website filtering to help block what he can access on the internet.
Hope this helps,
Shawn
