APC Magazine was able to get a copy and install service pack 1 beta for Windows Vista. Not unlike the usually patch which are standalone, the update comes fully integrated with a 3.2 DVD ISO. I seriously doubt though that it will be the release medium when goes live.

Not to be confused with the two enhancement packs which were leaked to the public a few weeks ago, and then officially released by Microsoft, these updates address compatibility and performance features in Vista. SP1 adds a new maintenance application called ?Create a Recovery Disc?. This isn?t the same thing as creating a backup of the system to DVD ? instead this process creates a recovery DVD which you can use with system recovery options if you don?t have an original Windows DVD or you can?t access OEM recovery tools. APC claims that the performance of Vista SP1 has substantial advantages of non-SP1.
