Ever wonder where you stored a certain file on your computer? If you have the new Windows 7 or even Windows Vista on your computer, you won’t need any extra software to answer that question. The functionality already built into Windows 7 and Vista beats the performance offered by four free search programmes, the experts at Germany’s Computer Bild magazine found.

Both Windows 7 and Vista scored above the best add-on programme. Windows 7 rated 2.84 on a scale of 1 to 5, with lower scores better than higher ones, and Vista rated 2.97. The best add-on programme was rated 3.03.
