I have recently created window server 2019 at Hyper V 2012 R2 host. Yesterday I was doing patching, while applying the patches it was stuck so I turned it off and again started it. Since then, it asks every time "Why did the computer shutdown unexpectedly" ?
I entered comment but same question again and again. even if I do soft reboot still same window. So my team is asking why does it come everytime

    I did some analysis of Mini dump file. I found that cluster had initiated reboot of server. I went in more detail then I found that the node went in non-responsive mode and cluster trigger an auto reboot of node to recover its health. So now the question is why node went in non responsive mode?
    I check with my colleague, one of them tried copying a heavy data and due to some reason server was hung so I am sure this caused this reboot problem. I asked MS to avoid this in future then they suggest.

    1. Update NIC drive
    2. Setup Network RSS

    Set-NetadapterRss -Name “Management NIC 1” -BaseProcessorNumber 2 –MaxprocessorNumber 63

    Hi,

    Thank you for your posting!

    Based on your descriptions, I agree with @Dave Patrick , you can go to Computer Configuration > Administrative Templates > System > "Display Shutdown Event Tracker", and set "Display Shutdown Event Tracker" as Disabled.

    If you still cannot solve your issue, you can try other solutions in this blog and more information about your issue like the causes can be found in the same blog as well:

    Thank you for your support!

    Best regards
