Here you go www dot dropbox dot com/sh/eebcglk0uw07wai/lZcWf2UF7_ the files are from DP 64-bit version, and I might have applied a tweak or something, because I've found two versions of shsxs.dll - a modified file and the original backed up, so I'm attaching them both.
Thanks I've ectracted the windows start button orb from the dev preview .dll to use with classic shell so it looks like this. I think this start button was meant for windows 8 so I'm using it with RTM version & Classic Shell. pretty cool
