Microsoft Windows Vista Service Pack 2 Pre-Beta Released
Microsoft began distributing a pre-beta release of Windows Vista Service Pack 2 just a few days after announcing a second service pack for Windows Vista which according to Microsoft would come out before the release of the next Microsoft operating system Windows 7
The pre-beta release is distributed to a select group of testers who have to run a program that adds a few keys to their Registry which enables the download of Windows Vista service pack 2 on Windows Update.
The release which has the build number 6002.16489 has a size between 290.7 MB to 296.9 MB. It contains all released updates but no obvious changes or additional features according to Within Windows
KB955430 is the hotfix that has to be installed after making the changes to the Windows Registry. After installing that hotfix the real Windows Vista Service Pack 2 download becomes visible in Windows Update.
It will probably be only a matter of time until the Registry changes leak on the Internet which would enable the Service Pack 2 downloads for anyone making the changes to their Registry.
