My folders search instead of opening in WinXP

I was monkeying around changing icons and now whenever I double click on a folder it starts a windows search instead of opening it. If I right click on it open is still an option, but the top and bold one is search.

Any ideas what I’ve done and how to fix it?

Not sure what you did but try going to control panel, folder options, general, and click on reset defaults

Here you go:
