The rationale is that we do not want users who aren't IT-savvy users to restart their machines without saving their important documents. It's quite annoying to see that pop-up message. Is there a way to suppress the patch reboot in WSUS? Is there a way to customize the pop-up by adding more text into the message to give users more meaningful instruction?
To the best of my knowledge, the message itself cannot be customized, but I imagine you could put a pop-up notice in this script of some kind without too much difficulty. For instance, the first lines of the script could be an ECHO message that provides the needed text, followed by a PAUSE command to wait for user input.
