Cannot load KERNEL Symbols with WinDbg after KB4019472 update RRS feed

  • Question

  • I'm using Microsoft Windows 10 Enterprise 10.0.14393 Version 1607 RU on VmWare in Debug Mode, and i ran into this issue. A few days ago a new update KB4019472 was installed automatically. After that, when i rebooted the windows, and connected with windbg i got this output, after trying to get the list of running processes:

    WINDBG>!process 0 0
    NT symbols are incorrect, please fix symbols

    Here is some test output with !sym noisy

    WINDBG>!sym noisy
    noisy mode - symbol prompts onWINDBG>.reload nt

    DBGHELP: ntkrnlmp.pdb - file not found
    *** ERROR: Symbol file could not be found.  Defaulted to export symbols for ntkrnlmp.exe - 
    DBGHELP: nt - export symbols

    I do not have any firewall/proxy, my IE works absolutely fine, and everything was ok, until this new update. I tried to download symbols from here:

    manually, into C:\Symbols folder, where my symbols is stored, but it didn't help.  Here is my full .sympath:

    Symbol search path is: SRV*c:\Symbols*
    Expanded Symbol search path is: srv*c:\symbols*
    ************* Symbol Path validation summary **************
    Response                         Time (ms)     Location
    Deferred                                       SRV*c:\Symbols*
    Can someone help, and maybe give me some location where i can download the correct symbols manually?

  • Sorry, looks for me symbols are not yet available on ms-symbol-server for new modules.  
    The symbol packages on
    Download Windows Symbol Packages
    are as a rule of thumb outdated.
    According to this may issue feedback through e-mail.
    recommended way to contact MS about missing pdbs is by email.
    Also looks like
    is monitored by the relevant team

    With kind regards
