I have been diving into Powershell for methods to deal with my WSUS better. I have noticed that an update gives the option of Approve or ApproveForOptionalInstall.
Whilte I can find many articles how to perform this I really don't know why I would pick one over the other.
When I approve through the WSUS GUI there is just the Approve option and you can optionally install it on the client or hide it. I suspect the group policy rules such as forced reboots if idle were active it might do something different than what I am observing in my environment, but I am guessing at this point.
Also, which option does the Approve in WSUS correspond to?
