Creating Alternative New Folder Command

I used a TechRep.Com article suggested procedure to create a “New Folder” button on my Windows Explorer tool bar. The procedure required adding a registry command. I was sure I followed the written procedures to a tee, but it didn’t happen so I used the procedures also provided to remove the registry command. Now when ever I double click on a folder in the main Explorer window it goes into the search window instead of opening the selected folder. Can anyone suggest a way to correct this problem.
