I use xampp as well, and I've modded it a bit to resemble x10's servers. This way I can try out things and when I'm sure it works, I can simply push it to my webspace.
I've already had problems with WAMP under vista but never from Xampp under Vista.
I when over the list of past programs, and none of then catch my eye... anyways, for the freeware part of the site, I prefer to download directly from the official website, or cnet.
