I wanted to make everyone aware of this via a link to my team's blog site.  Our top Win 7 issue right now is related to properly activating Windows 7 and Windows 2008 R2 clients and servers.  This is somewhat a servicing issue but somewhat a volume license issue, so I felt it was relevant.  This is in regards to how to properly install KB968912, which is the KMS update for Windows 7 and 2008 R2 clients.  More information can be found on our teams blog link below:
