Windows Vista build 5487

Windows Vista build 5487 is a pre-RC1 build of Windows Vista, which was reuploaded to BetaArchive by Grabberslasher on 29 January 2020 (after originally being leaked on 7 August 2006) alongside Windows Longhorn build 4033 (idx01).

History
German technology news website WinFuture.de released 57 screenshots of it on 2 August 2006, then the build itself was shared online in China five days later on 7 August, but it became lost shortly after. A torrent ostensibly containing this build was uploaded on 3 February 2019, but was not downloaded before it was lost owing to a lack of seeders.

Changes

 * It's the earliest available build stating itself as RC 1 instead of Beta 2 on watermark.
 * The Windows orb seen while logging in has decreased in size and resembles that of the RTM.
 * Slightly changed the appearance of the login screen to resemble the final version.
 * Changed many parts of the OOBE.
 * The setup and login screen now use the backgrounds seen in the RTM.
 * "Folder Options", "Fonts", "Mouse", "Sound", "Sync Center", "System" and "Welcome Center" applets received new icons in the Control Panel.

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.
