A little utility launched around the same time as Vista RC1. It's called XML Notepad 2006, and is available for download here. I think it got lost in all the Vista excitement, plus it doesn't carry the 'Windows Live' moniker like all the other apps coming out of Redmond lately. Anyway, you don't need to be a developer to find a million uses for this little gem. For instance, how many applications these days output log file information in XML format instead of text? By default, double-clicking on these XML files opens IE - and we all know how usable that is :|

Just like regular Windows Notepad, XML Notepad 2006 can both read from and write to XML files. So, after you finish playing with Vista, take a trip over to the Microsoft Download Center and grab a copy of XML Notepad 2006.
