A friend in the city of Santa Maria, Rio Grande do Sul, Brazil while reading these blogs: http://blogs.forumpcs.com.br/noticias/2010/08/29/patch-kb2028560-maior-performance-grafica-directx-11-no-windows-7/ http://www.forumpcs.com.br/comunidade/viewtopic.php?f=33&t=270752#p2427531 came across comments about hotfixes for Win7 Dx11 and posted the following links (x86 and x64): http://www.microsoft.com/downloads/details.aspx?FamilyId=b607f3ee-61ef-4069-97c6-d8a8b90b40a5&displaylang=en http://www.microsoft.com/downloads/details.aspx?FamilyId=e04dd3bd-c34b-42ef-978b-10b73e7d5bba&displaylang=en These are not posted as WU/MU updates but they enhance DX11. I checked them out and there appear to be four updates shown on each page that are applicable. Figured I'd mention them here so you can verify and post for inclusion in the Win7 Toolkit as applicable
