Any time you open a file or navigate to a web page, your Acer laptop keeps a record. Anyone who accesses your computer could potentially view those history files and discover what documents you have been viewing or websites you have been visiting. If you want to keep your computer habits private, delete the history files so that no one else can view your recently visited websites or program files.
