Windows 10 Shutdown - Restarts iMac

[Summez]

Hi,

I have a late 2015 5K iMac running Windows 10 Pro. When I try to shutdown the machine using the start menu the system immediately reboots into macOS. I have disabled Fast boot and it has made no difference.

Anyone have any ideas how to fix this

Many Thanks

Did you install the the Apple drivers in your Windows 10 install? If you did use the included Control panel to select what go boot into into!

Yes have installed the drivers. To clarify when I click shutdown in Windows the system immediately restarts, as I have macOS as my default startup disk the Mac boots into macOS
