How to replace release build version fastfat.sys with debug build version?

Hi All,
I need to use debug build version fastfat.sys to debug my FS driver.
However, after I built the debug version fastfat.sys from ISF DDK and
replaced the release build in OS, it looks like OS doesn’t allow me to
do
that. After reboot, OS replaces my debug version driver with
original release build again.
How can I replace the release version fastfat.sys with my debug build?

Thanks a lot.

Search for “Windows File Protection” on Microsoft site. It has a description
how to disable it.

Switch off System File Protection feature, there were ways of doing this.

Look up “Mapping Driver Files” in the WinDbg doccumentation. It explains
how to configure the debugger to overwrite driver files on the target
automatically.
