Windows 7 and Windows Server 2008 R2 Service Pack 2 has been released to Technet subscribers and IT professionals for a month or so, but Microsoft has released it to the public. I’ve been using it for a while, and have had zero problems with it. Of course, it is still beta, so YMMV. Grab it if you want to try it, it is basically a roll up of all updates to date. Choose the “No Guided Experience” for the no registering version.
