  • Hello,

    you need the version at the end of the list as already mentioned, AFAIK the above ones are for debugging and some language specific version.

    In your case windows6.1-KB976932-X64.exe should be the correct one.

  • what is the diference between  FRE and CHK.


    as per the details in the "Instructions" section of the download page:

    unless you are debugging Windows itself, the file you want is:
    windows6.1-KB976932-X64.exe - This application installs Sp1 to a 64-bit machine running Windows 7 or Windows Server 2008 R2

    PS: FRE means "check free" so this is the what the regular/normal product is built as.
    CHK means "checks enabled" and is also known as the "debug" build. this has deeper tracing enabled for testing.
    further information: 
    if you are running the debug you might want the symbols files installed locally.
