I'm used to build FASTFAT from WDK samples and replace it on my Windows 10 VM using WinDbg mapping file, so that I can step into it through its source code and learn more about file system internals. However, I'm not able to do it anymore using a recent version of Windows 10 (21H2), even disabling driver signature enforcement, having the binary signed using the test certificate and enabling Test Signing via BCDEDIT, although MS web site (updated at 5/18/2022) states I can do it.
"You can build a private version of this file system and use it as a replacement for the native driver."
Is there anything new I'm missing?
Thanks in advance,
