I just clicked the link Richard.Hein provided on search.microsoft.com , and it's actually the 4th if you count the 'Editor's choice'. Apparently, the Editor wants me to go to a forum site to figure out where the product is located.
Then, over on the right side of the screen, the 'related downloads' seem to want me to download PS 1.0 instead of 2.0.
Last, though, is that the link that supposedly takes me to powershell 2.0 ACTUALLY takes me to Windows Management Framework which happens to include powershell 2.0. But wait, over on the right side of that page are more links that refer to searches for powershell 2.0, powershell v 2, and powershell 2.
Ya know what, microsoft.com? All that vagueness is a pain in the @ss and far too complicated and I don't have the time to wade through it, so I'll skip it. See how that works? You lost a convert to what is probably a cool product because your search sucks and has sucked since its inception.
