Need some help.

Earlier I was changing some things and changed something I regret now. You know when you right click on your desktop and you can click new then there is a list of thing you can choose from. Well a month or two ago I took .zip file off the list and I don't remember how I did that. So if anyone knows how and could tell me that would be great. I know this doesn't relate to crossfire, but there isn't a help subsection in the General section.
