So I just updated my FanControl and noticed it had a replacement for WinRing0. A bit annoying to deal with because it might conflict with WinRing0 if you still have it installed. In my case, I was using OpenRGB and uninstalling that doesn't remove WinRing0.
- Uninstall all software that use WinRing0
- Boot into Safe Mode, manually remove from drivers folder
- Load RegEdit and remove any entry with WinRing0
- Reboot
- Uninstall all software that use PawnIO and reinstall
- You could install PawnIO separately first then install FanControl
