I am planning to Deploy WSUS, so that I can install windows Updates on Servers.
However I do not want my servers to get rebooted during the production time.
I need to install the updates between 12am and 5am every day, since my servers will be set up by group on WSUS, and each group will be updated on a separate day between 12am and 5am.
** My concern is, let's say a server needs 15 Updates, and when the updates get installed one at a time, the update 1 will require reboot, then 2,3,4 will not require reboot, then 5 will require reboot, then 6.7,8,9 will not require reboot, then update 10 will require reboot, then 11,12,13,14, will not require reboot, and update 15 will require reboot.
in this case how many times the server will reboot, in order to install all 15 updates? is ts gonna reboot 4 times or just one time ?
***another case is, if a server needs 50 updates, but it has installed 40 updates and it ran out of time. I mean it is already 5am ….how do I configure WSUS to pick up the rest of the updates install next scheduled time, in case it runs out of the time window ?
Any help from an expert who has Actually used WSUS, will be very much appreciated.
