The poster of the thread let's everyone know that a new beta desktop search bar has been released by MS. He goes on to say that he has no familiarity with the competition but he points out how useful this desktop search bar looks. he then gives a good example shortcut that can be used to search metalink. He also suggests that this search bar is faster than searching through outlook or the Windows Explorer.
As I said the story caught my eye as it could be possible that some issues occur such as with the google desktop search. I talked about this recently in a post called "Bruce Schneier talks about google desktop search security" in my own blog. Of course there may not be any issues at all, I have not tested the MS desktop bar.
