Every time you browse the internet, your information is stored in cookies and browser cache. When you use an app, your activity is stored in Application History. When you simply browse the computer and open files, the activity is stored in Recent Documents in Start Menu. How would you remove all traces of user activity and history without having to remove them manually one by one?
There are many tools that can do such job, but most of them require installation. ZeroTrace is a free portable tool for Windows that has recently grabbed my attention. I can now use a public computer and simply run this tool at the end to erase all my activity and history, thus, not worrying about my privacy anymore.
By default you will see Cookies Eraser window, where you can remove all cookies from your default web browser. To remove system, application, or Internet History go to System/Internet History tab.
As you can see from the screenshot above, you can not only remove the common Web Browser cache and Start Menu/Recent Documents History, but can also empty the recycle bin and remove Adobe Flash Player and WinDVD Cache.
When you hit Clean Up button, it will first shred the files before removal so that they can never be recovered again. It is both a light-weight and easy-to-use tool that works on all versions of Windows.
