how do I check what websites someone visited on my computer when history has been deleted?
It depends on whether you are a home user or a networked user, to a point. Some Network Administrators have it set up so that they can monitor what websites are being viewed by all others on the network (such as those that monitor you while you work if for example you work in a Call Center.)
If you are lacking this kind of system however, I do not believe that you're going to be able to pull that information up.
after deleting the history from the computer .you can not see the websites that have the user have visited.
history is used to see the the websites which has been opened by the user.
if the history has been deleted we can not know the visited websites.
I'll get you to the closest thing to it:
Control panel > Internet options > Under browsing history click "Settings" > View files
Shows stuff from your temporary internet files, you can see stuff where clearing your history didn't do.
