Just saw this on Twitter, apparently a new post RC build of Windows 7 has leaked…again. Apart from that, there seems to be a new branding wallpaper included with this update that shows the recent nature oriented Windows logo at a higher resolution using the traditional Windows flag colors. What I particularly love about this background is the simplicity of it. I do like the Welcome Screen background in the Release Candidate, but I believe there is just too much use of those subtle waves. The background picture now hosted on UXEvangelist blog is just the perfect balance of beauty and simplicity without the crowded look of the present welcome screen in build 7100.

New Windows 7 wallpaper

I believe using this background, minus the Windows logo of course would be perfect. Your thoughts.
