    Is it possible to mod shell32.dll in Windows 8.1?


    I'm using Windows 8.1, and I still haven't been able to modify shell32.dll (using Resource Hacker). Every time I do, it results in a BSOD. I can modify shell32.dll.mui just fine, but shell32.dll will break when I try to mod it. Also, modding authui.dll will break activation now. This kind of stuff didn't happen in previous versions of Windows, so what's the deal with Windows 8.1? I read somewhere that Windows now checks certain files for digital signatures, and that it won't use certain files that don't have a Microsoft signature on it. Is this true? And if so, is there any way around this? Maybe there's a way to get Windows to stop checking for signatures? Or is something else causing this? Any information on this would be useful. Thanks in advance.

    It could simply be that Microsoft is trying to lock things down that really don't need customizing so as to prevent infections of the various kinds around that screw up Windows. Apple also doesn't allow much capability in that area.

    They are doing this for the reason listed above and to help prevent piracy.

    This has been tried in the Windows 8 early days. Modifying ones shell32.dll file will render your system unbootable. We have come to find out that there really is no need to modify the shell32 file and can achieve the same results via other paths.

    Just got back from my grandson's funeral. Decided to check shell32.dll, on my Win7 64-bit there's more than 2 dozen versions in different subFolders of Windows.

    Just wanted to update here that modifying authui.dll does not actually break activation. Rather, it seems to break the login screen. Modifying basebrd.dll will break activation though.

    So back to shell32.dll. What if I were to extract a resource from it, and then import it to shell32.dll.mui and modify it from there? Would this work?

    Would it be possible to stop Windows from checking from a digital signature somehow? Like, in a method similar to patching Windows to use unsigned themes?

    I remember, vaguely, something from several years ago where a person wanted different icons and thought to modify that file, it didn't work. But there was something that one could use to store icons in a .dll file to make them available to the user, just can't recall the details. Maybe something here will help:

    That could be useful, although I also want to modify other resources, not just icons.

    So does anybody know exactly which file checks for a Microsoft digital signature?
