I want to check one thing.  Please try to downgrade your mudfish version to v4.5.0 found at http://mudfish.net/releases/ link then check whether this issue still is existing.  If it's solved with v4.5.0, it means there's a problem at new WFP driver which is shipping since v4.5.1.  However even if it's same with v4.5.0, it means it's completely another issue.

After downgraded to v4.5.0, the shutdown problem gone.

After tried using v4.5.0 for few days, I realised each time my pc is on for whole day and I opened mudfish, when I shutdown the pc, the problem comes again. But if I just open mudfish and pc for a while and shutdown again for experiement purpose, it seem to be fine.

Please check with this new one https://mudfish.net/releases/mudfish-4.5.3-x86_64-win2k-setup.exe

After installed v4.5.3, the shutdown problem still exist.
