Some info relating to your question....HTG Explains: Does Clearing Your Browser History Really Delete It?
There are an abundance of guides that tell you to locate index.dat files and use third party software to open and view them. Index.dat files do indeed contain logs of websites visited, but they aren’t useful if the browsing history has been cleared.
The biggest problem is that modern browsers no longer use index.dat files; the last browser to use them was Internet Explorer 9. So, we ran some tests with Internet Explorer 9, just to see if this method was useful for someone who’s running outdated software. Using Index.dat Suite, we were able to recover some browsing history, but after clearing it, the data inside the index.dat file disappeared.
If you need to grab the browsing history off of a computer before it gets cleared, the index.dat file makes for a good repository of sites visited, but it’s useless if the history is cleared before you can get to it. If you want to investigate index.dat files for yourself, click the link above to download the necessary software, and click the “View History” icon to have the program automatically scan for index.dat files and list the sites your computer has visited.
Where else can my history be recovered from?
It’s worth remembering that your entire internet browsing history is stored somewhere, whether temporarily or permanently, and whether by your ISP, the government, or whoever else decides to cache your list of browsed sites.
Typically, a warrant for the information would be required to get your ISP to release the details.
