I am preparing to patch multiple 2012R2 servers in mulitple offline networks that haven't been patched in over 2 years, so trying to get an understanding of the expected behavior during the installation process. If I use the settings I have defined below, will the servers just keep downloading and installing updates until they are fully patched or is there an interval that starts when you schedule the maintenance and stops after a certain period of time? Let's say there are 200 patches needed on Server A, they have all been approved in WSUS, and I schedule the installation as defined below... will Server A keep downloading and installing even if it takes until Sunday?
Use option #4 – Auto download and schedule the install
Deselect “Install during automatic maintenance”
Set “6 – Every Friday” for the scheduled install day
Set “17:00” for the scheduled install time
