When you surf on the internet or run certain
applications on your computer, Windows will silently compile a very
comprehensive record of you and your online activities whether you
know it or not. It provides chances for others to peak your
privacies especially when you are on a shared or public computer.
Therefore knowing how to clear the traces left behind on a computer
is important to prevent your privacies being disclosed.
First let us explore what kinds of histories are recorded by
Browser History 每 stores every website you have visited and can be
easily accessed through your browser.
Internet Cache 每 stores data from the web pages you visited.
Autocomplete form history 每 stores everything you type in a web
page, including your name, email, credit card information,
Cookies 每 files that a web site creates and stores on your
computer. They are used by certain websites to know your name,
shopping preferences and other information about you. Though most
cookies are harmless, they do create a problem for your privacy.
Index.dat files 每 contain records of all your online activities,
including internet histories, cache, and cookies. Because an
Index.dat file is used by Windows all the time, removing it is not a
easy job. Most users have to rely on privacy cleaning software to
delete such files.
Windows temporary files 每 created by Windows and programs on your
computer. Windows temporary files not only reveal your privacy, but
also get more and more clustered to occupy valuable disk space. For
example, even when a program is uninstalled, the temp files created
by the program will still be there.
Windows search history - After you have searched for an item using
Windows Explorer, Windows will automatically keep a record of the
search. And this search history will be visible to anyone who begins
a new search.
Recent documents 每 files and documents you have recently opened
and worked with.
Recently run programs 每 Programs you have recently run.

complete privacy clean is to use a privacy cleaner.

and applications. You are allowed to choose the ones to clean or
