I am to understand you want to delete the addresses in Internet Explorer?
If thats it than you go while in IE Tools, Internet Options and in the history area click on the box that says Clear History. Hope thats what you wanted.

Just delete the ones you don't want.
You'll notice that there all numbered ( 1,2,3,4 )...just make sure to rename some so they all stay numbered in order again
