Exchange services stopped and fails to start

Exchange Server 2016 CU7
Windows Server 2012 R2
All Exchange services suddenly stopped working except "Search host controller" and "Server Extension for Windows Server backup"
Topology gets error 1053 if I try starting it. Most other servicess get 1068 due to dependencies.
Interestingly some non-exchange services were disabled. "WWW Publishing Service" and "WMI" I was able to enable and start these and they remain enabled after a reboot.
Not sure what caused this.
Tried running updates but it fails to do a security update for CU7 (KB4045655).

I am in the process of downloading the Exchange ISO to see If I can do an installation repair.
If I restore whole VM from backup would there be any AD complications as there is separate Domain Controller?

Any suggestions would be appreciated.

Thanks.
