    Unregistering shell DLL's from command script


    Is it possible to unregister shell extension DLL's from a command script? Whenever I run "rundll32 /u path\to\whatever.dll" command lines from a script, I always get the error:

    I've tried running the script from an elevated command prompt window, and I've tried specifying the full \syswow64 and \system32 paths to rundll32.exe. I'm not going to modify registry permissions to get this to work.

    I have several shell extensions that I would like to automate the unregistration of, because doing it manually is a hassle.

    :)
     

  2. Ribbon missing in the task explorer, the libraries and also the text which appears on the title bar are also missing.

    Ok. You have a software named OldNewExplorer (OldNewExplorer64.dll) in your computer, which I think injects into Explorer to remove the ribbon.
    See if you can remove it via Programs and Features (Right-click Start > Programs and Features)

    Look for entries related to:

    1. OldNewExplorer

    2. StartIsBack

    Or if you locate the file "OldNewExplorer64.dll", you may try unregistering it from Command Prompt (Admin). To unregister the module:

    regsvr32 /u OldNewExplorer64.dll

    include the full path.. must be in a folder under Program Files.

    If DllUnRegister succeeds, restart Windows.
