I have found a couple of filthy shortcuts on my desktop, and inappropriate photos in several folders. I suspect that this is the work of one of my sons, but don't know which. Every time I check, the cookies have been cleared,  the Internet Explorer history has been deleted and the "save history for_ days" has been reset to "0".

 

I have been told that my computer saves a permanent record of all activity that cannot be easily deleted, and have seen references to such on TV cop shows.

 

Is this true?

 

If so, how do I access this history to see where my boys have been surfing? Will it show me the times of use and access to each web site? (I will be able to tell which is doing what by the times.) 

 

Thanks in advance for any help and/or advice.
