Rename multiple Windows files with one click

Yahoo! Tech has a way to rename multiple files into one category with a numbering scheme using only Windows Explorer. Just follow along with highlighting your files. Then click F2 and rename the file name. Click OK and you’re done. So if you named it “vaction beach pictures”, the rest of the files will follow suit and be named:
vacation beach pictures (1), vacation beach pictures (2), vacation beach pictures (3), etc.
Useful? I suppose. The parentheses are still something that is a Windows only annoying formating. But if you can get over that, this is a good way to do batches of files in one click without any utilities.
