Windows Vista build 5487

Windows Vista build 5487 is a pre-RC1 build of Windows Vista. WinFuture.de leaked 57 screenshots of it on 2 August 2006. This build was originally leaked on 7 August 2006 in China, but it became relost. On 23 January 2020, this build was listed on a thread by UX.Unleaked blog founder Grabberslasher to be leaked to the BetaArchive FTP. It was eventually leaked again to BetaArchive on 29 January 2020 alongside Windows Longhorn build 4033 (idx01).

Graphics Driver
The default VGA graphics adapter is very buggy, often having the screen flicker through resolutions and cannot have resolutions higher than 800x600 pixels. However, if you upgrade from a previous build, you can have 1024x768 and higher.
