How do I retreive deleted history
Unfortunately unless you are using a Operating system like Linux you wont be able to pull them from the dead, unless you have something that went to your recycling bin which normally doenst happen for web browsing history... Sorry! :-(
You can't - once it's deleted, it's gone.
Your only hope is if you created a backup to a point int time before the history was deleted or the files are still in the recycling bin.
Sorry to say, once you deleted history on your computer then you will not be able to access it or find it.
