Apparently, in the EULA of this version of SP1, it stated that the release is RTL version. After installing SP1 RC Refresh 2, system properties will only show “Service Pack 1″ without any build version, and there is no longer any “Evaluation Copy” watermark in the bottom right corner of desktop. And probably there is no expiry date to this version of test build too, though you won’t want to keep it after final version been released.

There are many unofficial rumors on the possible release date of RTM gold version of Vista SP1, from the earliest first week of February, 15th or 16th February, or the later the same date with official launch of Windows Server 2008. But one thing is for sure, Microsoft is still committed to release Vista SP1 in the first quarter of 2008.
