There is no specific setting which will undelete browsing history, but you can try couple of workarounds,
like doing a system restore
and also there is a hidden file named "index.dat", you can search for that file in your c:\ drive
[to unhide hidden files, click >> start->control panel->folder options->view(tab)-> select "show hidden files and folders"]
and once you are able to successfully search that file, right click on that file, and select open with options and try and open it with any text editor program [notepad, wordpad or Microsoft word].
Hope this helps.
There are also many data recovery softwares in the market, i will try and create a Hub on them in few days!
