Windows Server 2016 allows a maximum of 12 active hours. This needs to be increased.
active hours on the update screen can be a maximum of 12 hours. this needs to be extended to 23 hours. Many servers are actively used for more than 12 hours by users from multiple shifts and reboots should not take place while users are accessing files on the server.
I second and third this. Shocking this "idea" has only garnered 2 (now 3) votes since Mar 2019...perhaps because it was done anonymously? Either way, 12 hours for server? Way too low. I would argue the same for client systems, but then again, maybe I'm the only one in IT who works an "adjusted" schedule...10-12 hours per day over the course of the 24 hours.
