I've upgraded from build 7057 to 7077.  The first fix I've noticed is that now my XP machine (Ziggo2) shows up in the network as it should now.  In build 7057 a Vista machine would show up in the network fine but not XP pro SP3.  There is a bit of lag every time I open the &quot;Network&quot; from the start menu until all the items show up.

I've found no new issues to report and can't think of anything that made things difficult in the previous build.  I've also been able to enable display thumbnailed icons for .flv files after installing the 64 bit version of FFDshow  and a registry hack... but not all .flv files are displaying a thumbnail image in icon view.  There is no &quot;thumbanail&quot; view in 7 just 3 sizes of icons and image and video files should display as thumbnails in icon view if you have everything setup right.  Here's the registry hack to get .flv thumbs - should work in vista too:
