Assuming you're referring to the text entry fields on websites in Internet Explorer, go Tools->Internet Options->Content, click on AutoComplete, then click Clear Forms. You can also uncheck all of the boxes to prevent it from remembering future data.
If you're speaking of the Search feature in Windows (Start->Search), it's a horse of a different color...go Start->Search, click Change Preferences, and click Turn Off Autocomplete.
Hope this helps,
I am so excited in using my computer but noticed that everytime I enter a title of what I want to look up, the drop down has many titles that I have entered. In the seach window it is getting pretty long.
Does anyone know how to clear this up? Please make it easy if possible. I do well when instructions are in step by step format.
I have Windows XP
