No son uses our laptop in between. If I use it sometimes can funny requests from the erotic area, etc. I would like to control on which pages he drives around because he always deletes everything after he uses the laptop. I do not know myself so well. There are such keyloggers. Which is good for Windows 10. Which is also invisible when you start the laptop
Take the thing and go to a pc shop. Let you set up there for the curious sonhnemann own user account, for the same time youth protection is installed. You are then the "administrator" at the lappi and your son is just a user with very well-cut right.

Think of the router, there are models that log all pages on which the computer is surfed, which has gone through him on the Internet, conveniently you can read the log file later, as you will probably then different I think now better than a keylogger. Greeting
If I could get my hands on my laptop I would put a Linux distribution on it and set up a user for your son who will get everything logged. And he has no way to delete it. So at any time would have the overview what a short drive for nonsense. Of course I would not do that for free.
There's another option called Mint Nanny. Works only under a Linux distribution (Linux Mint). So you can lock various Internet addresses and words, so that the person has no way in the browser to use that. Likewise, times can be set for the user and Comfortable (even as a layman) can restrict the use of the programs.
So if you want to monitor your son better as a layman, it would be best to install a Linux distribution on your laptop and use it. Because with Linux your short does not know itself and even if it takes a while.
