Unfortunately the kids will reset 'options' to 'delete browsing history on exit'

As do most people who don't want to build up terrabytes of cookies, browsing history and temp files! A proxy server or router is, however, not on the local desktop and provided you do not let the kids into that device or let them by-pass it, you can still check the browsing history.

Or, as me and Ruth have both said, even if you don't do it - Let them belive you have and, every now and again, just throw in the odd comment like "What were you doing on such and such a site at 10:03 last night?" Usualy is enough to frighten them:-)
