Windows .exe crashes

Windows crashes

When userland utilities crash, for example zpool.exe, zfs.exe and similar, the best way to send the developers a crash stack is to;

Install the Registry snippet to enable crash dumps of the zpool.exe, zfs.exe executables. It is installed automatically into

C:\Program Files\OpenZFS on Windows\EnableOpenZFSLocalCrashDumps.reg

Or you can grab a copy directly from github: EnableOpenZFSLocalCrashDumps.reg

Make the program crash again, it will write crash dumps into:

%ProgramData%\OpenZFS\

ie, something like C:\ProgramData\OpenZFS\zpool.12345.dmp

Attach the dump file to an Issue ticket created at: https://github.com/openzfsonwindows/openzfs/issues

You can run DisableOpenZFSLocalCrashDumps.reg to undo the changes above but there is no real urgency to do so. The EnableOpenZFSLocalCrashDumps.reg script explicitly only enables dumps for zpool.exe and zfs.exe. Nothing else.
