Windows Vista build 5087

Windows Vista build 5087 is an unleaked pre-Beta 1 build of Windows Vista. This build was shown and demonstrated in the Gnomedex 2005 conference, showcasing the new IE 7 beta and particularly the RSS feed support (hence the buildtag). This build also features a screensaver that is able to update dynamically with photos and info over the internet. A channel9 video, Longhorn "Heart" RSS, features this build, but due to the low quality the buildtag cannot be seen. The only evidence that proves that the build is 5087 is the mention that the showcased build will be shown on the Gnomedex conference the next day. As of 2022, it remains unleaked.
