On the off chance that you read my blog and not Scott Hanselman's (shame on you) then I wanted to draw your attention to some invaluable registry tweaks he just posted - especially if you've been forced into installing Windows Desktop Search 3.0 to enable Outlook Instant Search - but also if you are a developer.
The first is how to make the normal windows search the default again after installing Windows Desktop Search, the second is how to get the full text search to search through *every* file (such as .cs or .java ones). The latter tip is one I always do when I build a new Windows box, but the former is a new annoyance I was struggling with. I can see why the new behaviors are the defaults for "regular" users - but it would have been nice if there was a way to change the defaults in the UI without resorting to regedit...
