    It seems the -N option in the 1st command is not detected ( something like "invalid commutator" or "invalid switch")
    The 2nd command goes well, but it looks like the 3rd one does nothing (no error but no message)

    I restarted but the error is still there

    OK - please post new event logs (they'll show if the hosts file is OK now)

    The file seems pretty empty, I uploaded the all etc directory

    Nah - it's the Application and System event logs I need please (although what you've shown already shows that it worked, I need to see the effect on the event system reports)

    No problem

    That's cleared the System log markedly

    Unfortunately it doesn't seem to have done much for the Application log.

    There appears to be a major problem with the NvStream service - but I don't think it's relevant here.

    Please upload the following logs, if you can find them...

    C:\Windows\servicing\Sessions\Sessions.xml
    C:\Windows\winsxs\poqexec.log
    C:\Windows\inf\setupapi.dev.log

    This update (KB2943357) appears to have been consistently failing with the same error since August 2014, when it was released.
    I'm getting no real help from the new files

    I really don't think there's a lot more that I can do, except point you in the direction of a repair install - Repair Install

    So it took me a while but I downloaded the Windows 7 Home Premium sp1 64 bits (x19 59009) from this link, I unzipped it and launched the setup.exe. Everything went fine untill it reboots for the 1st time : an error occured :

    Then the computer restart again with a message indicating it was impossible to install this release of Windows.

    Any idea why?
