Windows 10 Enterprise 1809 UWF C++ API

Question

Hello.

I'm looking for C++ API which allows me to save files from Unified Write Filter overlay to actual hard drive. I have IoT application some part of written on .NET Framework and C#. Previously on Embedded version of Windows 7 I used P/Invoke, imported fbwflib.dll library and FbwfCommitFile method. Now on Windows 10 Enterprise 1809 there is no File Based Write Filter and no previously mentioned library. I found only UWF_Volume WMI class and method CommitFile and it works, but I don't want use all that Managment Classes and Managment Objects in my code. So, is there is an analog of fbwflib.dll for Unified Write Filter on Windows 10 Enterprise 1809?

Answer 1

The UWF WMI provider is all that Microsoft has provided for UWF, which has been that way since Windows 8 Embedded Standard. They also only provided WMI API support for Shell Launcher and Keyboard filter. I developed utilities for all three using the WMI APO:

You have already written a C# with the UWF WMI commit, but I have source code example as part of my book downloads for enable and disable calls: https://annabooks.com/Book_SGWin10IoTE.html. 

It might not be what you want, but you could create a C# DLL that is accessible to C++: https://stackoverflow.com/questions/13293888/how-to-call-a-c-sharp-library-from-native-c-using-c-cli-and-ijw
