you are right, i tried now to install another Windows 7 security update & the process gone smoothly, but when i tried to re-download & install the above failed updates, still nothing !!
by the way, the microsoft fix it, doesn't work for me, it shows up the following error, check this image
i tried to install any optional language from windows update, but it also fails !!
i can't do the steps in post #8 , the temp/sand folder tip, cause the expand command doesn't work for me, cause all the failed updates are .exe not .msu, so i can't execute that command
so what to do next ?
