We have started to implement the User Deferral interface. Our logic to enable it on an application update is any/all of these:
1: Blocking app(s) need to be closed
2: Restart required following install
3: Popup will occur during/after installation
For #2, there are some applications that do not have a managed process list defined nor anything to key off of while still often requiring a restart to finalize. "Microsoft Visual C++ 2015-2022 x64" is an example of one such application.
For this scenario, it would be useful to add an option to "Always Notify" to the Manage Conflicting Processes interface that contains the same settings as "Notify the user to close the application".
