Whenever you use your laptop, Windows 8.1 automatically saves data about the programs, folders and documents you open, your browsing history and the items you delete. This information is readily available to anyone who has access to your computer and knows where to look. To remove your historical data, navigate to each location that has the settings to delete your information -- such as the Internet Properties utility, the Recycle Bin and the Taskbar and Navigation Properties utility.
