how to delete saved passwords without deleteing all the history

HI everyone
It's a simple question
How to delete only saved passwords from the browser's (IE8) history.I need the other things.

Thanks

From the Tools menu in IE8, select Internet Options.

On the General tab, under "Browsing history", click Delete.

Check the item(s) you want to delete:

◦Temporary Internet files (copies of web pages, images, and media that are saved for faster viewing)
◦Cookies
◦History (the lists of web sites you have visited)
◦Form data (saved information you have typed into forms)
◦Passwords
◦InPrivate Filtering data (saved data used by InPrivate Filtering to detect where web sites may be automatically sharing details about your visit)

To delete everything, uncheck Preserve Favorites website data and check all the other options.

Click Delete.
