Press the Ctrl button and the H button at the same time. A window on the side of your screen will appear with your search history, click and delete. Also, you can delete your history on your web browser tool bar. If you have internet explorer, it is on the right side of the toolbar and if you have Firefox, it is on the top left side of your tool bar. If you use internet explorer and you want to browse the web without anyone being able to see your search history, then right click on the internet explorer shortcut while looking at your desktop page. One of the options available should say, "Start InPrivate Browsing". Click on that, you can surf the web without worrying about search history. If you can't find it, open a new tab while in internet explorer and look at the bottom middle part of the page. Underneath "Your most popular sites" you should see "InPrivate Browsing". Have fun.
