The most recent Windows 8 screenshots we've posted so far were from build 7910, but now there appear to be users who have managed to acquire build 7955. Although build 7955 has not leaked to the public, there's now a video that shows a little taste of Microsoft is working on to include in Windows 7's successor. As always, we must emphasize that this is still very early in Windows 8's development, so try not to start forming your opinion on the OS just yet.

The video, courtesy of the German website WinFuture, shows many features we have already seen in leaked screenshots: a new logon screen and a new user icon menu in the taskbar. The leaked video of Windows 8 may be short (less than three minutes), but it's the first of many to come.

We reported on the first leaked Windows 8 build earlier this week but we warned our readers that it was very old and from Milestone 1. The build string is purposefully hidden in this video, but it's clear (not just from the higher number) that this is a significantly later build. Sit tight as the leaks will definitely keep coming - after all partners now have access to Windows 8 builds on Microsoft Connect - and we'll make sure to keep you in the loop.
