As Brian Harry notes in his blog post (New TFS Power Toys Available!), the Team Foundation Power Toys are now available for download: Download Team Foundation Server Power Toys. Previously, these power toys were only available in the SDK. If you haven't seen it, you should also give this post from Brian a read as well: A Bit on Power Toy Philosophy.
In addition, Brian also noted in his post that customers who use the Team Foundation Server MSSCCI Provider can now receive official support from Microsoft Support Services. Previously, this add-in was only supported through the Team Foundation Server - Version Control Forum.
