Windows Update settings - Restart options
In Windows Update on Server 2016 and beyond, there is the Restart options, which allows you to Schedule a time to restart and finish installing updates.
The problem is you can only turn this on once the updates have fully completed installed.
Instead of having to wait for the update to install, you should be allowed to Schedule the Restart time from this menu ONCE YOU HAVE ALREADY BEGUN to install updates. It's very annoying to have to wait for hours or however long, to then later have to go back and schedule the restart. You should be able to set it right away once you begin the install of updates. Perhaps, if the updates fail, then maybe it can be configured to automatically NOT reboot if there's a problem

Also can there be a reboot window set for example 1-2am each day if needed.
Or cant the 12 hour limitation on active hours be removed?
The entire ability to schedule when updates are applied and the system reboots has been broken for years. 2012 was the last usable server OS MS made, everything since is just a desktop OS that barely works with server functions partially crammed into it. MS no longer makes a server OS suitable for business let alone enterprise use. They seem to be doing what Apple did except they're not making it simple either, so it's a complete failure.
