Windows Vista build 5270

Windows Vista build 5270 is the official December 2005 Community Technology Preview build of Windows Vista, released to beta testers on 19 December 2005. It is the last build to include the "Professional Standard, "Professional Standard N" and the "Professional Enterprise" SKUs. They were replaced by build 5308 with the "Business", "Business (N)" and the "Enterprise" SKUs respectively.

Setup
Setup is practically similar to aforementioned builds of Vista, however the "Next" button is now much larger. The EULA has also been updated, and the wallpaper of the OOBE is essentially the same aurora wallpaper used in the first 2 stages of setup. Finally, the orb used during the OOBE has been changed with the start button orb, and it is positioned higher. You can even click on the orb, which has the same functionality as the finish button on the bottom-right.
